double _logb( doublex);
Parameters
- x
Double-precision floating-point value.

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.
