TypeScript - convert radians to degrees (rad to deg)
0 points
In this article, we're going to have a look at how to convert radians to degrees using TypeScript. In TypeScript, there is no built-in conversion method. It is necessary to write your own one.
Conversion can be made with the following formula:
A simple implementation is presented below.
xxxxxxxxxx1
const radToDeg = (rad: number): number => {2
return rad * (180.0 / Math.PI);3
};4
5
// Usage example:6
console.log(radToDeg(0)); // 0.0 degrees7
console.log(radToDeg(Math.PI / 2)); // 90.0 degrees8
console.log(radToDeg(Math.PI)); // 180.0 degrees9
10
console.log(radToDeg(3.141592653589793 / 6)); // ~30 degrees11
console.log(radToDeg(3.141592653589793 / 4)); // 45 degrees12
console.log(radToDeg(3.141592653589793 / 2)); // 90 degrees13
console.log(radToDeg(3.141592653589793)); // 180 degrees14
console.log(radToDeg(3.141592653589793 * 1.5)); // 270 degrees15
console.log(radToDeg(3.141592653589793 * 2)); // 360 degreesOutput:
