Return value notes

Returns an integer that is the integer value of val rounded towards negative infinity (return <= val).

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.
