Binary to Octal

[Luke15]

I really need some basic help on converting binary to octal as its for an assignment.

 

Is there any simplistic way in doing this?

 

Thanks.

 

Luke.

Take a binary number like 01001011 which is 75.

 

Split it into 3 bit sections from right to left.

 

01 001 011

 

Convert each one into the decimal number

 

01 = 1

001 = 1

011 = 3

 

So the octal equivalent is 113.

Cheers dude, much appreciated.

 

I have to do a Binary to Oct, Hex and Floating Point Assignment

Conversions to Oct and Hex are simple. For octal, convert binary into groups of 3 bits, for hex groups of 4 bits, and convert each group into a digit. Just make sure you start grouping starting with lowest bit.

 

Do you mean floating point in the binary? Same thing. Group everything to the right of the "decimal" point into groups of 3 or 4 bits. If you mean IEEE 32 bit floating point numbers, it is a bit tougher, but if you want to cheat, you can use a hex editor to get through it.
