Function: integer llCeil( float val );


0.0	Forced Delay
10.0	Energy

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

• float

–

Any valid float value

The returned value is 0x80000000 if the arithmetic result is outside of the range of valid integers -2147483648 <= val <= 2147483647.
