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.
