exp()

Computes the power of e.

  #include <math.h>
  
  double exp(double x);
  
  float expf(float x);
  
  long double expl(long double x);

Parameter

x

A value from which to compute.

Remarks

These functions returns ex, where e is the natural logarithm base value.

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

Listing: Example of exp() Usage


#include <math.h>

#include <stdio.h>

int main(void)

{

double x = 4.0;

printf("The natural logarithm base e raised to the\n");

printf("power of %f is %f.\n", x, exp(x));

return 0;

}

Output:

The natural logarithm base e raised to the power of 4.000000 is 
54.598150.
