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
<lsl>default {
state_entry()
{
llSay(0, "The rounded value of -4.9 is: "+(string)llRound(-4.9) );
//Returns "The rounded value of -4.9 is: -5"
llSay(0, "The rounded value of -4.1 is: "+(string)llRound(-4.1) );
//Returns "The rounded value of -4.1 is: -4"
llSay(0, "The rounded value of 4.5 is: "+(string)llRound(4.5) );
//Returns "The rounded value of 4.5 is: 5"
llSay(0, "The rounded value of 4.9 is: "+(string)llRound(4.9) );
//Returns "The rounded value of 4.9 is: 5"
llSay(0, "The rounded value of 4.1 is: "+(string)llRound(4.1) );
//Returns "The rounded value of 4.1 is: 4"
llSay(0, "The rounded value of -4.5 is: "+(string)llRound(-4.5) );
//Returns "The rounded value of -4.5 is: -4"
