integer llCeil(float fval)

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

The float value to be rounded up.

Returns the nearest integer value that is greater than or equal to fval.

• The function returns -2147483648 (Hex. 0x80000000) for float values of 2147483648.0 or bigger (including Infinity), or less than -2147483648.0 (including -Infinity), or NaN.

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

• llRound rounds to nearest integer.
• llFloor rounds always towards negative infinity (e.g. 1.1 is rounded down to 1.0 and -1.1 is rounded down to -2.0).
• float type and associated caveats and limitations.
