How to programmatically determine whether a given binary/decimal number contains a specific binary place value
I'm trying to find the most efficicent method for evaluating a given number and determining which binary place values it is made up of. For example:
168 = 1010 1000 (is made up of the '128', '32' and '8' bits)
My goal is to be able to return a boolean value for each place value, indicating whether it is contained within the given number. I'm hoping there may be a "built-in" method for doing this simpler than coding the math manually! Does anyone have any ideas? Thanks!

Use the "AND" logical operator. For example:
If 168 AND 128 = 128 then
'128 bit is set
Else
'128 bit is not set
End If
If 168 AND 128 = 128 then
'128 bit is set
Else
'128 bit is not set
End If

Outstanding! works great, frodoman. Wim_Bl, thanks for the input, but the article wasn't specific to what I was looking for - I'm already converting binary to decimal and vice versa.
Thanks again all!
Thanks again all!
Glad I could help.
this link should prove helpful, it converts decimal to binary and vice versa:
