Calculate the length of the hypotenuse for a right-angled triangle
#include <math.h> double hypot( double x, double y ); float hypotf( float x, float y );
These functions compute the length of the hypotenuse for a right triangle whose sides are x and y adjacent to the right angle. The calculation is equivalent to:
length = sqrt( x*x + y*y );
The length of the hypotenuse.
#include <stdio.h> #include <stdlib.h> #include <math.h> int main( void ) { printf( "%f\n", hypot( 3.0, 4.0 ) ); return EXIT_SUCCESS; }
produces the output:
5.000000
