syntax:

Clib.frexp(x, exp)

where:

x - number to work with.

exp - exponent used with a mantissa.

return:

number - mantissa with and absolute value between 0.5 and 1.0. If x is 0, return 0.

description:

This method breaks x into a normalized mantissa between 0.5 and 1.0 and calculates an integer exponent of 2 such that x == mantissa * 2 ^ exponent. The return is normalized mantissa between 0.5 and 1.0, or 0. The exponent used is in x. See Clib.ldexp().
