/**
* Inverse the sign of a value, apply a unary minus operation.
*
* For matrices, the function is evaluated element wise. Boolean values and
* strings will be converted to a number. For complex numbers, both real and
* complex value are inverted.
*
* Syntax:
*
* math.unaryMinus(x)
*
* Examples:
*
* math.unaryMinus(3.5) // returns -3.5
* math.unaryMinus(-4.2) // returns 4.2
*
* See also:
*
* add, subtract, unaryPlus
*
* @param {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} x Number to be inverted.
* @return {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} Returns the value with inverted sign.
