# Number

An integer number.

A Number is an integer such as `42` or `-42`. More precisely, a Number is a signed 32-bit integer (two’s complement).

### Declare a number variable

You can assign a number to a variable:

``let num = 42;``

### Arithmetic operators

The following arithmetic operators work on numbers and return a Number:

• addition: `1 + 3`
• subtraction: `1 - 3`
• multiplication: `3 * 2`
• integer division: `7 / 3`
• modulo is available through the math library

### Relational operators

The following relational operators work on numbers and return a Boolean:

• equality: `(3 + 1) = 4`
• inequality: `3 != 4`
• less or equal than: `3 <= 4`
• less than: `3 < 4`
• greater or equal than : `4 >= 3`
• greater than: `4 > 3`

### Functions that return a number

Some functions return a number, which you can store in a variable.

``let abs = Math.abs(-42);``

### Math functions

The math library includes math related functions. For example, the `min` function returns the minimum value of two input parameters `x` and `y`:

``let lowest = Math.min(-42, 1000);``
