Compiler plug-in that provides mathematical functions.
All identifier and function names are defined case-insensitive and can not be abbreviated with the exception of remainder (shortenable up to remain) and random (shortenable up to rand).
Constants:
| Type | Name | Description |
|---|---|---|
| Float | PI | The ratio of a circle's circumference to its diameter. |
| Float | E | Euler's number. |
Functions:
| Return Type | Name | Signature | Description |
|---|---|---|---|
| Float | abs | Integer | Computes the absolute value of an integer number. |
| Float | abs | Float | Computes the absolute value of a floating point number. |
| Float | ceil | Float | Returns the nearest integer not less than the given value. |
| Float | floor | Float | Returns the nearest integer not greater than the given value. |
| Float | trunc | Float | Returns the nearest integer not greater in magnitude than the given value. |
| Float | round | Float | Returns the nearest integer, rounding away from zero in halfway cases. |
| Integer | rint | Float | Returns the nearest integer, rounding away from zero in halfway cases. |
