|函数名=Function:integer llCeil(float val);
|参数=参数：float val-Any valid float value
|返回值=返回值:Return an integer that is the integer value of val rounded towards positive infinity(return>=val).

|注意事项=The returned value is -2147483648(Ox80000000)if the arithmetic result is outside of the range of valid integers(-2147483648 to 2147483647)
