About this Base Converter Base-2 to base-62 are accepted. "A"
stands for 10, "Z" for 35, "a" (lower-case) for 36 and "z"
(lower-case) for 61. Decimals are supported. This is a custom
function because PHP's base_convert() doesn't accept decimals
and only goes up to base-36. It's only as precise as PHP is, so
don't blindly copy the smallest decimal thinking it will always
be correct. Is there any standard for displaying numbers higher
than base-36? I've used lowercase letters to go up to base-62,
but I couldn't find if that's what is commonly done. (Then
again, I guess nothing is commonly done, since anything beyond
base-16 doesn't really have much use, to my knowledge.) Fun
game: Enter your name and supply base-36 (or higher) as the
starting base and see what number you get in another base. My
first name in base-38 for instance returns EPKCO in base-42.
What's this about? A base is the system with which numbers are
displayed. If we talk about base-n, the system has n characters
