sprintf and negative number sign?

[lawpoop@gmail.com]

Hello all -

I have sprintf formatting a number that goes on a report. I'm using
%05.2f to change 5.5 to 05.50, for example. However, I'm having a
problem with negative values -- I get -3.43, for example, because with
the sign, the whole length of the string is 5 characters.

I want a number that always has the tens place and the hundredths
decimal place, and the sign only when the number is negative. For
example:
05.50
-01.22
55.07
-80.00
00.40

How do I get what I want? Obviously, I don't really understand the
syntax of sprintf. Thanks!

Also note, I tried simply using %06.2f, and while that does give me
-03.33, it will give me 003.32 when the number is not negative. So,
any help is appreciated.

You can't achieve that with a single sprintf call, at least I don't
think it's possible.

Perhaps add a "+" to force the sign at the beginning and then delete it.
str_replace("+" , "", sprintf("%+06.2 f", 3.45));

sprintf("%c%05. 2f", $value < 0 ? '-' : ' ',$value);

sprintf('%s%05. 2f', $value < 0 ? '-' : '', abs($value));

sprintf('%s%05. 2f', $value < 0 ? '-' : '', abs($value));

Yes, thanks for fixing it. But space still need here so right variant is:
sprintf("%s%05. 2f", $value < 0 ? '-' : ' ',abs($value));
