Summary

Function: integer llCeil( float val );

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

• float val – Any valid float value

Caveats

  • The returned value is -2147483648 (0x80000000) if the arithmetic result is outside of the range of valid integers (-2147483648 to 2147483647)
