Function Documentation

Calculates the nominal annual interest rate, given the effective rate and the number of compounding periods per year.

The function is based on the following equation:

Example:

#include <iostream>
 
#include <codecogs/finance/banking/interestnominal.h>
 
int main(int argc, char *argv[])
{
  double rate;
  
  printf("Effective rate\tPeriods\tNominal rate\n");
  for (double a=0.0025; a<0.1; a+=0.005) 
	{
    rate=Finance::Banking::interestNominal(a, 4);
    printf("%f\t%i\t%f\n", a, 4, rate);
  }  
  return 1;
}
