Description

Operator (arithmetic); used for negating or subtracting.

Usage 1: When used for negating, it reverses the sign of the numerical `expression`.

Usage 2: When used for subtracting, it performs an arithmetic subtraction on two numerical expressions, subtracting `expression2` from `expression1`. When both expressions are integers, the difference is an integer. When either or both expressions are floating-point numbers, the difference is a floating-point number.

Example

Usage 1: The following statement reverses the sign of the expression 2 + 3.

    -(2 + 3)

The result is `-5`.

Usage 2: The following statement subtracts the integer 2 from the integer 5.

    5 - 2

The result is `3`, which is an integer.

Usage 2: The following statement subtracts the floating-point number 1.5 from the floating-point number 3.25.

    3.25 - 1.5

The result is `1.75`, which is a floating-point number.
