There's a pre-cursor to this - code to unpack and perform arbitrary floating-point.
There's also subtle problems in attempting up conversion such as float->double
alter the value:
print 1.4
$1 = 1.3999999999999999
vs:
print 1.4
1.4
someone into hard-core floating-point isn't going to accept the former.

See printf(3)'s "a" and "A" formats for a guidelines.
