The BITLSHIFT() function performs a bit-wise left shift operation of the first parameter. The number of bits to shift by is specified by the second parameter. Note that a negative number of bits to left shift by becomes a right shift.
De funksje BITLSHIFT () skood de bitjes fan de earste parameter in tal bits nei lofts. it tal bits nei lofts wurdt mei de twadde parameter oanjûn. Tink derom dat in negatyf nûmer in ferskowing nei rjochts bewurkmastert.
