## Math Operators

The common numeric operators below may be used in math expressions.

The plus character (`+`) between two numeric values produces the result of adding them together. If both values are of the `Number` type, the result will be a `Number`; otherwise the result will be `Decimal`.

Examples:

• `2 + 2`

• `[Count] + 1`

• `[Price] + [Tax]`

### Divide

The slash character (`/`) between two numeric values produces the result of dividing the left value by the right value. If both values are of the `Number` type, the result will be a `Number`; otherwise the result will be `Decimal`.

Examples:

• `4 / 2`

• `([Day Count] / 7.0)`

• `[Total] / [Unit Count]`

### Multiply

The asterisk character (`*`) between two numeric values produces the result of multiplying them together. If both values are of the `Number` type, the result will be a `Number`; otherwise the result will be `Decimal`.

Examples:

• `(10.0 * 10)`

• `[Week Count] * 7`

• `[Unit Cost] * [Unit Price]`

### Negate

The minus character (`-`) preceding a single numeric value produces the arithmetic negation of the value: a positive value becomes negative, a negative value becomes positive. The type of the result will match that of the original value.

Examples:

• `-18.56`

• `-[Unit Count]`

• `-([Seat Count] * [Gift Value])`

### Subtract

The minus character (`-`) between two numeric values produces the result of subtracting the right value from the left value. If both values are of the `Number` type, the result will be a `Number`; otherwise the result will be `Decimal`.

Examples:

• `124.0 - 18.9`

• `(14.0 - [Vacation Days Used])`

• `[Price] - [Discount]`

## Math Functions

Math functions may also be used anywhere math expressions may be used.

## Numeric Types

AppSheet understands two basic numeric data types:

`Decimal`: numbers that include a decimal point separating a whole number component from a fractional component. For example: `-0.03`, `0.0`, `3.14159`, `14.99`. Also known as a real number or floating-point number. The number of digits displayed after the decimal point (2 by default) can be changed in a `Decimal` column's configuration. The display format is also affected by the app user's locale.

`Number`: numbers that do not include a decimal point. For example: `-29`, `-5`, `0`, `732`, `4096`. Also known as integers or whole numbers.

Several other data types are based on the above:

`Percent` is a `Decimal` with special display characteristics. For example, a `Percent` value of `0.0` is displayed as 0%; `0.05` is displayed as 5%; `0.2` as 20%; and `1.0` as 100%.

`Price` is a `Decimal` with special display characteristics. For example, a `Price` value of `0.0` is displayed as \$0.00; `5.2` is displayed as \$5.20; `67.482` as \$67.48; and `100.0` as \$100.00. The currency symbol (`\$` by default) can be changed in a `Price` column's configuration.
