Library FunctionsFREXPSynopsis#include double frexp (double f, int * p)DescriptionThe frexp() function breaks a floating point number into a normalized fraction and an integral powerof 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 theresult are zero.Example#include #include voidmain (void){double f;int i;}f = frexp(23456.34, &i);printf("23456.34 = %f * 2^%d\n", f, i);See Alsoldexp()147
