C++ math log base
WebInteger binary logarithm. Returns the integral part of the logarithm of x , using FLT_RADIX as base for the logarithm. This is the exponent used internally by the machine to express the floating-point value x, when it uses a significand between 1.0 and FLT_RADIX, so that, for a positive x: x = significand * FLT_RADIX exponent. WebReturns the base-e exponential function of x, which is e raised to the power x: e x. Header provides a type-generic macro version of this function. This function is overloaded in and (see complex exp and valarray exp ).
