// # Sample
// Arithmetic Operators
//
// # Description
// Arithmetic operators in Q# are used to perform basic mathematical operations
// on numerical values. The arithmetic operators in Q# are `-` (negation), `+`,
// `-`, `*`, `/`, `%`, and `^`.

function Main() : Unit {

    // `-`, when applied to a single value on its right, negates the value.

    // The integer value `-32`.
    let integer = -32;

    // The integer value `32`.
    let integer = --32;

    // The integer value `-32`.
    let integer = ---32;

    // `+` adds two values together.

    // The integer value `42`.
    let integer = 10 + 32;

    // `-` subtracts the right-hand value from the left-hand value.

    // The integer value `-22`.
    let integer = 10 - 32;

    // `*` multiplies the two values together.

    // The integer value `320`.
    let integer = 10 * 32;

    // `/` divides the left-hand value by the right-hand value.
    // When the operands are both integers, the result is truncated to an integer.

    // The integer value `3`.
    let integer = 32 / 10;

    // The integer value `-3`.
    let integer = -32 / 10;

    // The double value `3.2`.
    let double = 32.0 / 10.0;

    // `%` gives the modulo of the left-hand value by the right-hand value.

    // The integer value `2`.
    let integer = 32 % 10;

    // The integer value `-2`.
    let integer = -32 % 10;

    // The integer value `2`.
    let integer = 32 % -10;

    // The integer value `-2`.
    let integer = -32 % -10;

    // `^` gives the exponent of the left-hand value raised to the power of the right-hand value.
    // When the operands are both integers, the right-hand value cannot be negative. This is
    // checked at runtime.

    // The integer value `81`.
    let integer = 3^4;

    // The integer value `-81`.
    let integer = -3^4;

    // The double value `256.0`.
    let double = 16.0^2.0;

    // The double value `-256.0`.
    let double = -16.0^2.0;

    // The double value `4.0`.
    let double = 16.0^0.5;

    // The double value `0.25`.
    let double = 16.0^ -0.5;
