# Comparison

Comparison operators are used to compare two variables, typically numbers.

## Operators

The Lua core is capable of the following comparison operators:

Less than: `<` Compares the left variable to the right variable. Returns `true` if the left is less than the right, otherwise returns `false`.

Greater than: `>` Compares the left variable to the right variable. Returns `true` if the left is greater than the right, otherwise returns `false`

Less than or equals: `<=` Compares the left variable to the right variable. Returns `false` if the left is greater than the right, otherwise returns ` true`. This is the logical opposite of the greater than operator.

Greater than or equals: `>=` Compares the left variable to the right variable. Returns `false` if the left is less than the right, otherwise returns `true`. This is the logical opposite of the less than operator.

Equals: `==` Compares the left variable to the right variable. Returns `true` if the two variables are equal, or `false` if they are not.

Not Equals: `~=` Compares the left variable to the right variable. Returns `false` if the two variables are equal (a few exceptions, see special cases), or `true` if they are not. This is the logical opposite of the equals operator.

## Special cases

• NaN (Not a Number) is the only Lua value that is not equal to itself.
• Table equality is by reference, not by value. This means that `{3} == {3}` is `false` because the two tables have different references/are at different locations in memory, even though they contain the same values. However, `local tbl = {3}; print(tbl == tbl)` is `true` as the reference is the same and they are considered the same table.
• Comparison can be overriden using metamethods.

gollark: 2026 and/or in a few hours if you specify the issue more precisely.
