Tricky code - tricky result. Do you think php-5.1 result is perfect? :)
BTW the difference is in implementation of %G format specifier.
It seems, now it tries to produce the shortest string representation of
float (I cannot remember why), but this is not conformed to POSIX
specification
Linux man:
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
signifi-
cant 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.
Probably it should be fixed.
Thanks. Dmitry.
