Do you mean the number of decimal places or the total number of digits?
For a complete description of printf and the format string for the C
language, take a look here (amongst other places):
http://en.wikipedia.org/wiki/Printf
Note though that AFL has limitations on what types of numbers it can
display.
As far as formatting floats goes, you can use a specification like
"%x.yf" where 'x' is the total number of displayed digits (including
the decimal point) and 'y' is the number of decimal places. If you
precede 'x' with zero (ie. %0x.yf) leading spaces will be replaced
with leading zeros.
Also note that if you specify less total digits than the number needs
to display the full value, it will still display the full number. So
if the value is 12345 and you specify %1.0f, it will still display
12345. If you don't specify 'x', eg. %.2f, it will use the minimum
number of characters necessary to display the number with two decimal
places, which is essentially the same as %1.2f as there will always be
at least one digit before the decimal point, even if it's zero.
