Some key points of printf(3)'s
g,G The double argument is converted in style f or e (or F or E
for G conversions). The precision specifies the number
of significant digits. If the precision is missing, 6
digits are given; if the precision is zero, it is
treated as 1. Style e is used if the exponent from its
conversion is less than -4 or greater than or equal to
the precision. Trailing zeros are removed from the
fractional part of the result; a decimal point appears
only if it is followed by at least one digit.
are not mentioned at all in perldoc -f sprintf, nor do the examples
there show cases like the below. As far as patches, perhaps just use
printf(3)'s.
This would cause some users to pass up %g, and end up posting:
-------------
Should the perl sprintf documentation be augmented? It says
Arguments are usually formatted to be only as wide as required to
display the given value.
But to get the versions on the right,
6.250000 6.25
12.500000 12.5
18.750000 18.75
25.000000 25
31.250000 31.25
I had to do
for ( 1 .. 5 ) {
my $f = $_ * 6.25;
my $s = $f;
$f =~ s/\.?0+$//;
printf "%f $s\n", $f;
}
