Converting between Denary & Binary
- When converting from denary to binary, you figure out which of the numbers is the highest and goes into the number you're trying to convert.
- You then subtract the total you're trying to make from that number - and you try to find the highest number that goes into that one.
- You continue to do this until you have the full number.
- When converting binary back into denary, you simply line up the digits into the table (Shown opposite) and add all the numbers that line up with the ones.
-
Converting between Binary & Hexadecimal
- A hex digit can be represented as any of these 16 digits (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F)
- To convert into hexadecimal from binary, you need to separate the digits into blocks of 4 and convert them into denary. From there you simply put the two digits together.
- To convert from hexadecimal into denary (via binary) you simply separate the two digits and find their binary equivalents, then convert those back into denary.
