The function RealF can be used to convert a floating point value into a string, with a specified number of decimal digits. But to fit the string into a greater container prepending 0 we must write our own function. (The one here proposed has no a flag for the alignment of the result inside the containing string)
PROC newRealF(es, fl, digit, len=0, zeros=TRUE)
DEF s, t, i
IF (len = 0) OR (len < (digit+3))
RETURN RealF(es, fl, digit)
ELSE
s := String(len)
t := RealF(es, fl, digit)
FOR i := 0 TO len-EstrLen(t)-1 DO StrAdd(s, IF zeros THEN '0' ELSE ' ')
StrAdd(s, t)
StrCopy(es, s)
DisposeLink(s)

define p(n, c) {
auto d, d[], f, f[], i, m, r, s, v
s = scale /* Save original scale. */
if (n < 0) {

}
/* d[] takes digits before the radix point. */

if (r != 0) {
while (r % 10 == 0) { /* Prune digits. */
f -= 1
r /= 10
}
for (i = 0; i < f; i++) {
f[i] = r % 10
r /= 10
}
}
/* Pad "0" digits to reach c characters. */
c -= d
if (f > 0) c -= 1 + f
for (1; c > 0; c--) "0" /* Print "0". */
/* i = index, m = maximum index, r = digit to print. */
m = d + f
for (i = 1; i <= m; i++) {
if (i <= d) r = d[d - i]
if (i > d) r = f[m - i]

COBOL
This is actually the easiest kind of numeric output to achieve in COBOL, because it requires no adjustments from the way numbers are stored internally (in fixed-point decimal). Each variable declaration requires a PIC or PICTURE clause describing the kind of data that will be stored there. In this case, we have 9 (a decimal digit), repeated five times; then V, the decimal point (cf. French virgule); and then three more decimal digits. Other terms that can appear in PICTURE clauses include A (a letter of the alphabet), X (a character), and Z (a decimal digit to be printed with leading spaces instead of leading zeros).

In [https://wiki.formulae.org/Formatted_numeric_output this] page you can see the solution of this task.
Fōrmulæ programs are not textual, visualization/edition of programs is done showing/manipulating structures but not text ([http://wiki.formulae.org/Editing_F%C5%8Drmul%C3%A6_expressions more info]). Moreover, there can be multiple visual representations of the same program. Even though it is possible to have textual representation —i.e. XML, JSON— they are intended for transportation effects more than visualization and edition.
The option to show Fōrmulæ programs and their results is showing images. Unfortunately images cannot be uploaded in Rosetta Code.
Forth
Forth has a rather rich set of number formatting words, which makes formatted output very flexible but sometime cumbersome.
Here one way to generate the required output. Note that the number generated is NOT truncated to the field width. If you wish to truncate the number, remove #s and 1- from the definition. (The 1- is necessary because #s always generates at least one digit, even if it's zero.)
\ format 'n' digits of the double word 'd'
: #n ( d n -- d ) 0 ?do # loop ;
\ ud.0 prints an unsigned double
: ud.0 ( d n -- ) <# 1- #n #s #> type ;
\ d.0 prints a signed double
: d.0 ( d n -- ) >r tuck dabs <# r> 1- #n #s rot sign #> type ;
Usage example:
d 8 ud.0
Result: 00000123 ok
Type: -123 s>d 8 d.0
Result: -00000123 ok

Detail
== Forth's number formatting words are different than many other languages because they are active code rather than using a pattern string. This small set of seven routines ( >DIGIT <# #> # #S HOLD SIGN ) allow arbitrary number formatting of double precision and single precision numbers. The number is created in a "hold' buffer the output is typically a Forth style stack-string consisting of an address and a length.
Typical of Forth the using the formatting routines means putting things in reverse order. We are also free to create a mnemonic name that gives a reminder at how numbers will appear.
To replicate the example for this task we could write:
: '.' [CHAR] . HOLD ; \ HOLD inserts a character into the number string
\ right side . left side
: 0000#.### ( d -- addr len) DABS <# # # # '.' # # # # # #> ;
At the console we can input a double number, execute the format routine and type the resulting string.
7.125 0000#.### TYPE 000007.125 ok
Fortran
{{works with|Fortran|90 and later}} Using standard data edit descriptors it is only possible to precede Integer data with leading zeros.
INTEGER :: number = 7125
WRITE(*,"(I8.8)") number ! Prints 00007125
On the other hand
One can engage in trickery via FORMAT statements, in particular the T format option. Unlike actual tab settings which on a typewriter go to a particular column following, T''n'' means go to column ''n''.
INTEGER IV
REAL V
DATA V/7.125/ !A positive number.
IV = V !Grab the integer part.
WRITE (6,1) V,IV
1 FORMAT (F9.3,T1,I5.5)
END
Output is 00007.125 This would need adjustment for other sizes, but works as follows: The value part is printed (in the format system's working area) as "bbbb7.125" (b's standing for spaces), then the T1 moves the finger back to column one, and the I5.5 writes out "00007", the .5 addendum to I5 meaning print leading zeroes rather than leading spaces. It does not overwrite the subsequent ".125", and as no further output items appear the deed is done. Only later Fortran offers the addendum feature, but the Tab feature is much older.
Another approach would be to write forth a literal "0000" instead of the integer, but this is less flexible. In the absence of the .5 addendum, write the output to a character string (or equivalent), replace leading spaces by zeroes (watching out for negative numbers), and print the result.

Julia
Julia's @sprintf macro provides string formatting that is similar to that of the c function of the same name. Though easy to use and efficient, @sprintf has limited flexibility, as its format specification must be a string literal, precluding its use in dynamic formatting. Greater flexibility is available via the Formatting package, which provides an implementation of Python's format specification mini-language. This solution demonstrates both of these techniques to provide the leading zero padded floating point format suggested in the task description ("%09.3f").
using Printf test = [7.125, [rand()*10^rand(0:4) for i in 1:9]] println("Formatting some numbers with the @sprintf macro (using \"%09.3f\"):") for i in test println(@sprintf " %09.3f" i) end using Formatting println() println("The same thing using the Formatting package:") fe = FormatExpr(" {1:09.3f}") for i in test printfmtln(fe, i) end

## Sather
The Fill options should fill with any character, but it is still (!) not implemented; according to [http://www.icsi.berkeley.edu/~sather/Documentation/Library/LibraryBrowser/short-FMT.html ICSI Sather library documentation] (GNU Sather library documentation is missing) works only for string, bools and characters, but a test has revealed it does not work in either way (yet) (GNU Sather v1.2.3).
```sather
class MAIN is
main is
#OUT + #FMT("", 7.1257) + "\n";
#OUT + #FMT("", 7.1254) + "\n";
end;
end;
```
Luckly the C-like formats are supported too:
```sather
#OUT + #FMT("%09.3f", 7.125) + "\n";
```
