Hi David and All. Thanks all for the suggestions. My functions are more or less the same approach as the suggestions made so I'll stick with them.

Many thanks.

>>I have written my own number to binary to number function but I thought I would ask if there was an easier method. I am looking to take number eg 123456 and convert that into a binary string like "00000000000000011110001001000000". Is there a fast way to do this num to char-bin and back to number?
