Converting byte contents to one number?

Oldbitcollector (Jeff)

Question:

I have byte[noparse][[/noparse]0], byte1, and byte2....

byte[noparse][[/noparse]0] contains character 49 (a 1)
byte1 contains character 50 (a 2)
byte2 contains character 51 (a 3)

How do I combine these to create a singe number (123) in byte3?

for some reason the code command won't process this example.


Thanks
OBC

byte3 := (byte0-"0")*100 + (byte1-"0")*10 + (byte2-"0")

You can also do this in a loop with

byteVal[noparse][[/noparse] 3 ] := 0
repeat i from 0 to 2
   byteVal[noparse][[/noparse] 3 ] := byteVal[noparse][[/noparse] 3 ]*10 + byteVal[noparse][[/noparse] i ] - "0"

Thanks Mike, that loop did the trick.. Incorporated into Spudview for reading the image size.
