/**
|
|
* Compare two values. Returns 1 when x > y, -1 when x < y, and 0 when x == y.
|
|
*
|
|
* x and y are considered equal when the relative difference between x and y
|
|
* is smaller than the configured absTol and relTol. The function cannot be used to
|
|
* compare values smaller than approximately 2.22e-16.
|
|
*
|
|
* For matrices, the function is evaluated element wise.
|
|
* Strings are compared by their numerical value.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.compare(x, y)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.compare(6, 1) // returns 1
|
|
* math.compare(2, 3) // returns -1
|
|
* math.compare(7, 7) // returns 0
|
|
* math.compare('10', '2') // returns 1
|
|
* math.compare('1000', '1e3') // returns 0
|
|
*
|
|
* const a = math.unit('5 cm')
|
|
* const b = math.unit('40 mm')
|
|
* math.compare(a, b) // returns 1
|
|
*
|
|
* math.compare(2, [1, 2, 3]) // returns [1, 0, -1]
|
|
*
|
|
* See also:
|
|
*
|
|
* equal, unequal, smaller, smallerEq, larger, largerEq, compareNatural, compareText
|
|
*
|
|
* @param {number | BigNumber | bigint | Fraction | Unit | string | Array | Matrix} x First value to compare
|
|
* @param {number | BigNumber | bigint | Fraction | Unit | string | Array | Matrix} y Second value to compare
|
|
* @return {number | BigNumber | bigint | Fraction | Array | Matrix} Returns the result of the comparison:
|
|
* 1 when x > y, -1 when x < y, and 0 when x == y.
