clog()

Computes natural logarithms.

  #include <math.h> 
   double complex clog(double complex x); 
    float complex clogf(float complex x); 
   long double complex clogl(long double complex x);

Parameter

x

A complex value.

Remarks

These functions return log e x. If x < 0 , clog() assigns EDOM to errno. Use fpclassify() to check the validity of the result returned by clog().

This facility may not be available on configurations of the EWL that run on platforms that do not have floating-point math capabilities.
