Function: integer llRound( float val );
 11 Function ID 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 infinity of like signedness of val.

## Caveats

The function returns -2147483648 (0x80000000) if the nearest integer value to the input would be outside of the range of valid integers (-2147483648 to 2147483647)
