Function: integer llRound( float val );
 0 Forced Delay 10 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

```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"
}
}
```

## Notes

• 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.

```function integer llRound( float val );
