+   * 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.
