This is my sand box =frexp= We used frexp in mathematical purpose.The frexp is function which break the floating point     value into two part.first in mantissa and second in exponent.We can express x as floating point value, m as mantissa and n as exponent.In frexp ,the range of mantissa is always between 0.5 to 1.

format

 * double frexp(double x, int *exppr);
 * float frexpf(float x, int *exppr);
 * long double frexp1(long double x, int *exppr);

return value
The frexp function return mantissa.The exppr pointed to the location where exponent is stored.x=mantissa*2exponent
