# Functions

## 2.8 Functions

Functions were introduced in release 5. They may be used anywhere where a boolean or numeric expression is expected, such as the if/else and for statements, the Eval command and any other command parameters that support numeric expressions by this specification. Function names are not case sensitive.

For example, the following 'for' statement will iterate 10 times:

**for **(i=0; i<MAX(6,10,9); i=i+1) {

...

}

Supported functions (contact support if you need a custom one):

Function | Description |
---|---|

NOT(expression) | Boolean negation, 1 (means true) if the expression is not zero |

IF(condition,value_if_true,value_if_false) | Returns one value if the condition evaluates to true or the other if it evaluates to false |

RANDOM() | Produces a random number between 0 and 1 |

MIN(e1,e2, ...) | Returns the smallest of the given expressions |

MAX(e1,e2, ...) | Returns the biggest of the given expressions |

ABS(expression) | Returns the absolute (non-negative) value of the expression |

ROUND(expression,precision) | Rounds a value to a certain number of digits, uses the current rounding mode |

FLOOR(expression) | Rounds the value down to the nearest integer |

CEILING(expression) | Rounds the value up to the nearest integer |

RAD(expression) | Converts an angle measured in degrees to an approximately equivalent angle measured in radians |

DEG(expression) | Converts an angle measured in radians to an approximately equivalent angle measured in degrees |

FACT(expression) | Retuns the factorial value of an integer. Will return 1 for 0 or a negative number |
