expm1: returns the natural logarithm e raised to the arg power, minus 1( e^arg-1)

    
Declaration: float expm1f(float arg); 
             double expm1(double arg); 
             long double expm1l(long double arg);  
 

  

  #include <math.h>

  int main(void)
  {
     printf("Value of e to the first: %f.", expm1f(1.0));
  }
