Information about bit shift operand

[Gastone Berni Srl]

I would like to know if possible where I can find information on the use of SHL bit shift, perhaps with some programming examples.

[Sergio Bertana]

All information on the operators defined within the LogicLab environment can be found on User Manual. In this case, the SHL operator help reports:

• Descrizione: Shift a sinistra di input#0 per il numero di bit indicato da input #1 con riempimento di zero a destra.
• Numero di operandi: 2
• Tipo di dato input: Qualsiasi tipo numerico, Qualsiasi tipo numerico
• Tipo di dato output: Lo stesso di input #0
• Esempi: OUT := SHL( IN := 16#1000CAFE, 16 );  // OUT = 16#CAFE0000

In practice, shifting a value to the left is equivalent to multiplying it by 2.

Good morning Mr. Bertana, I always have a question to ask you regarding the SHL operator, but after SHL has done its job how can I bring it back to the beginning of the count.

Maybe I wasn't clear, but thanks anyway if you can help me.

Greetings.
