/**
|
||
|
|
* Unary plus operation.
|
||
|
|
* Boolean values and strings will be converted to a number, numeric values will be returned as is.
|
||
|
|
*
|
||
|
|
* For matrices, the function is evaluated element wise.
|
||
|
|
*
|
||
|
|
* Syntax:
|
||
|
|
*
|
||
|
|
* math.unaryPlus(x)
|
||
|
|
*
|
||
|
|
* Examples:
|
||
|
|
*
|
||
|
|
* math.unaryPlus(3.5) // returns 3.5
|
||
|
|
* math.unaryPlus(1) // returns 1
|
||
|
|
*
|
||
|
|
* See also:
|
||
|
|
*
|
||
|
|
* unaryMinus, add, subtract
|
||
|
|
*
|
||
|
|
* @param {number | BigNumber | Fraction | string | Complex | Unit | Array | Matrix} x
|
||
|
|
* Input value
|
||
|
|
* @return {number | BigNumber | Fraction | Complex | Unit | Array | Matrix}
|
||
|
|
* Returns the input value when numeric, converts to a number when input is non-numeric.
