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.
Doubles are double-precision numbers. They can represent any number exactly, except for numbers whose digits repeat infinitely.
Since Doubles can be either larger or more precise than what JSON parsers allow, many formats, such as JSON, serialize them as strings. For example:
The following table describes the operators that can be used with Doubles.
Operation | Description |
---|---|

>= |
TRUE for numerics that are greater than or equal to this one. |
!= |
TRUE for numerics that are not equal to this one. |
= |

+ |
Adds two numerics |
- |
