|函数名 = Function:  integer llFloor( float val );
|参数= 参数：float val – Any valid float value 
|返回值= 返回值：Returns an integer that is the integer value of val rounded towards negative infinity (return <= val).


|注意事项=The returned value is -2147483648 (0x80000000) if the arithmetic result is outside of the range of valid integers (-2147483648 to 2147483647 inclusive).
