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.
