# Money Datatype

Heads up! Numbers, Doubles, and Moneys are all numeric types, and can be compared and combined in functions. For example, you could multiply a money value by a number, or compare the values of a number and a double.

Monetary values are fixed precision numbers, as most currencies aren’t divisible beyond their smallest unit (ex. one cent). In most representations, they’re encoded as strings to preserve accuracy. For example:

That also persists into how they must be encoded in queries - monetary values must be quoted to retain their accuracy. For example: $where=salary > '90000'. The following table describes the operators that can be used with Money fields. Operation Description < TRUE for monetary values less than this one. <= TRUE for monetary values that are less than or equal to this one. > TRUE for monetary values that are greater than this one. >= TRUE for monetary values that are greater than or equal to this one. != TRUE for monetary values that are not equal to this one. = TRUE for monetary values that are equal to this one. IS NULL TRUE for monetary values that are NULL. IS NOT NULL TRUE for monetary values that are not NULL. + Adds two monetary values - Subtracts one monetary value from another * Multiplies two values, can be performed with numbers / Divides one value by another, can be performed with numbers The following table describes the functions that can be used with money fields. Keyword Name Description Availability Function Name Description Availability avg(...) Returns the average of a given set of numbers 2.0 and 2.1 between ... and ...
