But as ICENG and MP suggest converting binary to decimal or Hex or Octal isn't really hard and there are lots of on line calculators or explanations to do this.

in my experience 0 x 08 indicates octal code (base 8)

and 0 x 10 indicates decimal (base 10)

0 x 16 would indicate hexadecimal. (base 16)

Both octal and hex are simple shorthand ways to express big binary numbers

In octal you split the binary into groups of 3 binary digits each trio is considered a unique number so an octal number is made up of the decimal numbers 0 to 7 (7 being the largest decimal number you can show with 3 binary digits.

Hex is similar but uses 4 binary groups or quartets.

In this case as 4 binary digits can = up to 16 in decimal we have to contend with numbers that may be above 9 - we use the letters A, B, C D, E and F

So a hex number A= 10, B-11, C=12, D=13, E=14 and F=15

(4 binary digits = 0 to 15)

'0x08 to binary'
