Calculates the square root of a sum of squared double precision floating-point values.
Include
<math.h>
Prototype
double hypot(double x, double y);
Arguments
x
y
Return Value
Returns the square root of a sum of the arguments squared, being the
hypotenuse of a right-angled triangle with perpendicular sides of length
x
and y
.
Remarks
A range error might occur.
Example
#include <math.h>
#include <stdio.h>
int main(void)
{
double x, y, h;
x = 1.75;
y = 2.05
h = hypot(x, y);
printf("The hypotenuse of a right-angle triangle with other side lengths of %f and %f is %f\n", x, y, h);
}
Example Output
The hypotenuse of a right-angle triangle with other side lengths of 1.750000 and 2.050000 is 2.695366
