/**
|
|
* Test whether a value is an numeric value.
|
|
*
|
|
* The function is evaluated element-wise in case of Array or Matrix input.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.isNumeric(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.isNumeric(2) // returns true
|
|
* math.isNumeric('2') // returns false
|
|
* math.hasNumericValue('2') // returns true
|
|
* math.isNumeric(0) // returns true
|
|
* math.isNumeric(math.bignumber(500)) // returns true
|
|
* math.isNumeric(math.fraction(4)) // returns true
|
|
* math.isNumeric(math.complex('2-4i') // returns false
|
|
* math.isNumeric([2.3, 'foo', false]) // returns [true, false, true]
|
|
*
|
|
* See also:
|
|
*
|
|
* isZero, isPositive, isNegative, isInteger, hasNumericValue
|
|
*
|
|
* @param {*} x Value to be tested
|
|
* @return {boolean} Returns true when `x` is a `number`, `BigNumber`,
|
|
* `Fraction`, or `boolean`. Returns false for other types.
|
|
* Throws an error in case of unknown types.
