Back to Home#### approximatelyEqual

mathbeginnerChecks 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`

.

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