log10()

Compute base-10 logarithms.

  #include <math.h>
  
  double log10(double x);
  
  float log10f(float x);
  
  long double log10l(long double x);

Parameter

x

A floating point value.

Remarks

This function returns log 10 x.

If x < 0, log10() assigns EDOM to errno. Use fpclassify() to check the validity of the result returned by log().

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