/**
|
|
* Test whether a value is NaN (not a number).
|
|
* The function supports types `number`, `BigNumber`, `Fraction`, `Unit` and `Complex`.
|
|
*
|
|
* The function is evaluated element-wise in case of Array or Matrix input.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.isNaN(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.isNaN(3) // returns false
|
|
* math.isNaN(NaN) // returns true
|
|
* math.isNaN(0) // returns false
|
|
* math.isNaN(math.bignumber(NaN)) // returns true
|
|
* math.isNaN(math.bignumber(0)) // returns false
|
|
* math.isNaN(math.fraction(-2, 5)) // returns false
|
|
* math.isNaN('-2') // returns false
|
|
* math.isNaN([2, 0, -3, NaN]) // returns [false, false, false, true]
|
|
*
|
|
* See also:
|
|
*
|
|
* isNumeric, isNegative, isPositive, isZero, isInteger
|
|
*
|
|
* @param {number | BigNumber | bigint | Fraction | Unit | Array | Matrix} x Value to be tested
|
|
* @return {boolean} Returns true when `x` is NaN.
|
|
* Throws an error in case of an unknown data type.
