Summary
Function: integer llFloor( float val );| 9 | Function ID |
| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns an integer that is the integer value of val rounded towards negative infinity (return <= val).
| • float | val | – | Any valid float value |
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 floor value of -4.5 is: "+(string)llFloor(-4.5) );
//Returns "The floor value of -4.5 is: -5"
llSay(0, "The floor value of -4.9 is: "+(string)llFloor(-4.9) );
//Returns "The floor value of -4.9 is: -5"
llSay(0, "The floor value of -4.1 is: "+(string)llFloor(-4.1) );
//Returns "The floor value of -4.1 is: -5"
llSay(0, "The floor value of 4.5 is: "+(string)llFloor(4.5) );
//Returns "The floor value of 4.5 is: 4"
llSay(0, "The floor value of 4.9 is: "+(string)llFloor(4.9) );
//Returns "The floor value of 4.9 is: 4"
llSay(0, "The floor value of 4.1 is: "+(string)llFloor(4.1) );
//Returns "The floor value of 4.1 is: 4"
}
}
Notes
- For positive values, it is quicker and shorter to simply cast the float to an integer. i=(integer)f is 32 bytes shorter than i=llFloor(f) (in Byte Code) and about 30 times faster in execution, while giving the same result.
