approximatelyEqual

Checks if two numbers are approximately equal to each other.

Use Math.abs() to compare the absolute difference of the two values to epsilon. Omit the third parameter, epsilon, to use a default value of 0.001.

typescript

export const approximatelyEqual = (
  v1: number,
  v2: number,
  epsilon: number = 0.001
) => Math.abs(v1 - v2) < epsilon;

typescript

approximatelyEqual(Math.PI / 2.0, 1.5708); // true
approximatelyEqual(Math.PI / 2.0, 1.5708, 0.000001); // false // 1.5707963267948966
