What is fmaxf in C?
Overview
The fmaxf() function in C is defined in the <math.h> header file. fmaxf() takes two arguments (x and y) of type float as input and returns the larger of the two numbers. The function is defined in the <math.h> header file as:
float fmaxf( float x, float y );
Examples
Below is an example of how to use fmaxf(). Using an example of and , we use the fmaxf() function to print the largest floating-point number.
#include<stdio.h>#include<math.h>int main() {float largest = fmaxf(3.3, 2.7);printf("The larger of the two numbers is: %f\n", largest);return 0;}
Below are the ways in which the results of the fmaxf() function vary for different values of x and y:
-
If
xisNot a Number (NaN),fmaxf()will returny, and vice versa -
If both inputs are
NaN, the return value is alsoNaN
The code below demonstrates these input values and their results:
#include<stdio.h>#include<math.h>int main() {printf("The larger of the two numbers if one is NAN is: %f\n", fmaxf(NAN, 2.7));printf("The larger of the two numbers if both are NAN is: %f\n", fmaxf(NAN, NAN));return 0;}
