What is the hypot() function in Swift?
Overview
The longest side of a right-angle triangle, and the side opposite to the right angle, is known as the hypotenuse in geometry.
The mathematical formula to calculate the hypotenuse’s length is known as the Pythagorean theorem and is as follows:
hypotenuse = sqrt( length^2 + base^2 )
The following figure shows the visual representation of the hypot() function:
Note: We need to import
Foundationin our code to use thehypot()function. We can import it usingimport Foundation.
Syntax
hypot(length, base)
Parameters
This function requires the length and base as parameters.
Return value
This function returns the hypotenuse of the right-angle triangle. The triangle’s length and base are passed as parameters.
Example
The code below shows the use of the hypot() function in Swift:
import Swiftimport Foundation//positive: length positive: baseprint ("The value of hypot(2.0,3.0) : ",hypot(2.0,3.0));//positive: length negative: baseprint ("The value of hypot(0.25,-2.0) : ",hypot(0.25,-2.0));//negative: length positive: baseprint ("The value of hypot(-10.0,2.0) : ",hypot(-10.0,2.0));//negative: length negative: baseprint ("The value of hypot(-0.5,-1.0) : ",hypot(-0.5,-1.0));
Explanation
- Line 2: We add the
Foundationheader required forhypot()function. - Line 5: We calculate the hypotenuse of the positive length and the positive base using
hypot(). - Line 8: We calculate the hypotenuse of the positive length and the negative base using
hypot(). - Line 11: We calculate the hypotenuse of the negative length and the positive base using
hypot().
- Line 14: We calculate the hypotenuse of the negative length and the negative base using
hypot().
