/**
* 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.
