/**
|
|
* Test whether two values are equal.
|
|
*
|
|
* The function tests whether the relative difference between x and y is
|
|
* smaller than the configured epsilon. The function cannot be used to
|
|
* compare values smaller than approximately 2.22e-16.
|
|
*
|
|
* For matrices, the function is evaluated element wise.
|
|
* In case of complex numbers, x.re must equal y.re, and x.im must equal y.im.
|
|
*
|
|
* Values `null` and `undefined` are compared strictly, thus `null` is only
|
|
* equal to `null` and nothing else, and `undefined` is only equal to
|
|
* `undefined` and nothing else. Strings are compared by their numerical value.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.equal(x, y)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.equal(2 + 2, 3) // returns false
|
|
* math.equal(2 + 2, 4) // returns true
|
|
*
|
|
* const a = math.unit('50 cm')
|
|
* const b = math.unit('5 m')
|
|
* math.equal(a, b) // returns true
|
|
*
|
|
* const c = [2, 5, 1]
|
|
* const d = [2, 7, 1]
|
|
*
|
|
* math.equal(c, d) // returns [true, false, true]
|
|
* math.deepEqual(c, d) // returns false
|
|
*
|
|
* math.equal("1000", "1e3") // returns true
|
|
* math.equal(0, null) // returns false
|
|
*
|
|
* See also:
|
|
*
|
|
* unequal, smaller, smallerEq, larger, largerEq, compare, deepEqual, equalText
|
|
*
|
|
* @param {number | BigNumber | boolean | Complex | Unit | string | Array | Matrix} x First value to compare
|
|
* @param {number | BigNumber | boolean | Complex | Unit | string | Array | Matrix} y Second value to compare
|
|
* @return {boolean | Array | Matrix} Returns true when the compared values are equal, else returns false
