Perl normally uses `double` for floating point numbers, even on 32-bit machines. You can find out what your `perl` uses as follows: `$ perl -V:nvtype nvtype='double';` [download] A `double` is an IEEE double-precision number on a desktop computer. As such, 8.95 is actually stored as 0x1.1E66666666666 * 2^3 = 8.949999999999999289457264239899814128875732421875.	[reply] [d/l] [select]
