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 infinity of like signedness of val.
Caveats
- The function returns
0x80000000
if the integer value nearest to val would be outside of the range of valid integers-2147483648 <= val <= 2147483647
.
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" // Note: the above result not -5 as would be expected, due to the inaccuracy involved in storing -4.5 as a float }}</lsl>
