/**
|
|
* 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 | bigint | Fraction | Complex | Unit | Array | Matrix} x Number to be inverted.
|
|
* @return {number | BigNumber | bigint | Fraction | Complex | Unit | Array | Matrix} Returns the value with inverted sign.
