FREXP
Synopsis
Description
The frexp() function breaks a floating point number into a normalized fraction and an integral power
of 2. The integer is stored into the int object pointed to by p. Its return value x is in the interval (0.5,
1.0) or zero, and f equals x times 2 raised to the power stored in *p. If f is zero, both parts of the
result are zero.
