## Operators in Airtable

Airtable operators

Operator

Symbol

Use

Example

Greater than

`>`

Compare if one number is greater than another

`IF(5 > 5 ...`

Less than

`<`

Compare if one number is less than another

`IF(5 < 5 ...`

Greater than or equal to

`>=`

Compare if one number is greater than or equal to another

`IF({Field A} >= {Field B} ...`

Less than or equal to

`<=`

Compare if one number is less than or equal to another

`IF({Field A} <= {Field B} ...`

Equal to

`=`

Compare if one value is equal to another value

`5 = 5`

Does not equal

`!=`

Check if one value is not equal to another value

`IF({Field A} != {Field B} ...`

## Greater and less than operators

#### NOTE

For the following examples, assume that you want to compare income against expenses on a weekly basis.

Greater than

First, check if income is greater than expenses. If income is greater than expenses, the result of the formula will be a 1 (meaning true), and if not, a 0 (meaning false).

`{Income} > {Expenses}`

Less than

Now, check if income is less than expenses. If income is less than expenses, the result of the formula will be a 1, and if not, a 0.

`{Income} < {Expenses}`

## Greater, less than, and equal to operators

Greater than or equal to

Similar to the formulas above, we can compare if income is greater than or equal to expenses (still returning a 1 or 0). The difference is most obvious in the below table when the Income and Expenses are equal—the formula returns 1.

`{Income} >= {Expenses}`

Less than or equal to

Now we can check the opposite, let's compare if income is less than or equal to expenses by changing the operator.

`{Income} <= {Expenses}`

## Equal and does not equal to operators

Equal

Check if income is exactly equal to expenses.

`{Income} = {Expenses}`

Does not equal

Likewise, we can check if a value is not equal to another by adding “!” before the “=” icon.

`{Income} != {Expenses}`
