float frexp10 (float x, short *exponent);

Splits floating point number into mantissa and exponent.

frexp10 calculates the mantissa m (a floating point greater than or equal to 0.1 and less than 1) and the integer value n, such that x equals m*10^n. frexp stores n in the integer that exponent points to, and returns the mantissa m.
Note: This routine is analogous to `frexp` in ANSI C math library, except using base ten rather than base two.
