llRound
function
Function syntax
integer llRound(float val// Number to round.
);- Returns
integer- Energy
- 10
If the absolute value of the tenths position is 4 or less, val is rounded off; otherwise, val is rounded towards positive infinity.
integer result = llRound(0.0);Caveats
Section titled “Caveats”- The returned value is -2147483648 (0x80000000) if the arithmetic result is outside of the range of valid integers (-2147483648 to 2147483647 inclusive).
Examples
Section titled “Examples”Example 1
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" }}- For positive values, it is quicker to add 0.5 to the value and cast to an integer. i=(integer)(f+0.5) produces less bytecode than i=
llRound(f)and is about 5 times faster in execution, while giving the same result.
