===== Function: llFloor =====

<code lsl2>
integer llFloor(float fval)
</code>

Round a $ty[float] down to the closest $ty[integer] less than or equal to it.

===== Parameters =====

=== fval ===
The $lty[float] value to be rounded down.

===== Return value =====

Returns the nearest $lty[integer] value that is less than or equal to $prm[fval].

===== Notes =====

  * The function returns -2147483648 (Hex. 0x80000000) for float values of 2147483648.0 (including $pinf) or bigger, or less than -2147483648.0 (including $minf), or $nan.

===== Short examples =====

<code lsl2>
integer i;
i = llFloor(3.0);    // i will become 3, which is less or equal to 3.0 (in this case, equal).
i = llFloor(3.001);  // i will become 3, not 4, because 4 is greater than 3.001 and the result must be less or equal.
i = llFloor(3.999);  // i will become 3
i = llFloor(4.0);    // i will become 4
i = llFloor(-3.0);   // i will become -3
i = llFloor(-3.001); // i will become -4, which is less or equal to -3.001 (in this case, less)
i = llFloor(-3.999); // i will become -4
i = llFloor(-4.0);   // i will become -4
