Discussion: More Math, but Fun This Time
Execute the code to understand the output and gain insights into recursive approximation.
We'll cover the following...
Run the code
Now, it's time to execute the code and observe the output.

#include <stdio.h>double phi(double p, int precision){while(precision)return( p + 1/phi(p, precision-1) );return(p);}int main(){double gr;gr = phi(1.0, 15);printf("Phi is %f\n", gr);return(0);}
Understanding the output
The code outputs the following line:
Phi is 1.618034
Code output
This is the golden ratio, represented by Greek letter phi,
