===== Function: llCeil =====

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

Round a float up to the closest integer greater than or equal to it.

===== Parameters =====

=== fval ===
The float value to be rounded up.

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

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

===== Notes =====

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

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

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