/**
|
|
* Test whether a value is an integer number.
|
|
* The function supports `number`, `BigNumber`, and `Fraction`.
|
|
*
|
|
* The function is evaluated element-wise in case of Array or Matrix input.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.isInteger(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* math.isInteger(2) // returns true
|
|
* math.isInteger(0) // returns true
|
|
* math.isInteger(0.5) // returns false
|
|
* math.isInteger(math.bignumber(500)) // returns true
|
|
* math.isInteger(math.fraction(4)) // returns true
|
|
* math.isInteger('3') // returns true
|
|
* math.isInteger([3, 0.5, -2]) // returns [true, false, true]
|
|
* math.isInteger(math.complex('2-4i')) // throws an error
|
|
*
|
|
* See also:
|
|
*
|
|
* isNumeric, isPositive, isNegative, isZero
|
|
*
|
|
* @param {number | BigNumber | bigint | Fraction | Array | Matrix} x Value to be tested
|
|
* @return {boolean} Returns true when `x` contains a numeric, integer value.
|
|
* Throws an error in case of an unknown data type.
