Manipulating numbers in Handel-C/C

[real]

Hi,

I have 4 numbers. I need to extract the first bit of each number and put them together to form a resulting binary number.

i.e. 12=00001100
100=01100100
4=00000100
5=00000101

So the first number I need would be 0001 and the second would be 0000 and so on. How would I go about implementing this in Handel-C or C.

Thanks

Ah. I think i've just remembered how to take the first bit of each of the numbers. I could logic AND the number with 0000001. But im still stuck on how to put the bits together.

Thank you for your reply.

So what I will do is this:

AND all the numbers with 0x1 to single out the first bit.

Then for the first number I do <<3, for the second <<2, the third <<1 and the fourth nothing. Then I add these together.

Thanks for your help.
