Integer Functions
Integer functions can round off values to integers.
This can be done in different ways: upwards or downwards.
Functions
The following functions are available for rounding off values.| Function | Description |
|---|---|
| Ceil(x) | Round towards plus infinity |
| Fix(x) | Round towards zero |
| Floor(x) | Round towards minus infinity |
| Round(x {,n}) | Round towards the nearest integer. With n you can specify the number of decimals of the resulting value. n can be a number from 0 to 9. |
