Summary
Function: integer llRound( float val );11 | Function ID |
0.0 | Forced Delay |
10.0 | Energy |
Returns the integer that val is closest to.
• float | val | – | Any valid float value |
If the absolute value of the tenths position is 4 or less, val is rounded off; otherwise, val is rounded towards positive infinity.
Caveats
- The returned value is -2147483648 (0x80000000) if the arithmetic result is outside of the range of valid integers (-2147483648 to 2147483647 inclusive).
Examples
