Extracts exponential value of double-precision floating-point argument.

double _logb(    doublex);

Parameters

  • x
    Double-precision floating-point value.

Return Values

_logb returns the unbiased exponential value of x.

Remarks

The _logb function extracts the exponential value of its double-precision floating-point argument x, as though x were represented with infinite range.

If the argument x is denormalized, it is treated as if it were normalized.

Header: stdlib.h.
