JavaScript: Convert radians to degrees
JavaScript Math: Exercise-34 with Solution
Write a JavaScript function to convert radians to degrees.
Test Data :
console.log(radians_to_degrees(0.7853981633974483));
45
Sample Solution-1:
JavaScript Code:
// Define a function named radians_to_degrees that converts radians to degrees.
function radians_to_degrees(radians)
{
// Store the value of pi.
var pi = Math.PI;
// Multiply radians by 180 divided by pi to convert to degrees.
return radians * (180/pi);
}
// Output the result of converting approximately 0.785 radians to degrees to the console.
console.log(radians_to_degrees(0.7853981633974483));
Output:
45

Sample Solution-2:
JavaScript Code:
// Define a function named radians_to_degrees that converts radians to degrees using an arrow function.
const radians_to_degrees = rad => (rad * 180.0) / Math.PI;
// Output the result of converting pi/2 radians to degrees to the console.
console.log(radians_to_degrees(Math.PI / 2));
// Output the result of converting approximately 0.785 radians to degrees to the console.
console.log(radians_to_degrees(0.7853981633974483));
Output:
