Number Systems

Our exercise last meeting in IT 1 was about number systems. According to our instructor, it is used to represent digital data. This digital data is represented by symbols called digits.

We were also taught how to do base conversions. Here are some steps:

Base-r to Decimal

Procedure:

1. Multiply each coefficient with the corresponding power of r.
2. Get the sum.

Decimal to Base-r

Procedure:

1. Divide integer by r.
2. Accumulate remainders.

Binary to Octal

Procedure:

1. Partition binary numbers into groups of 3.
2. Compute the decimal equivalent of each group.

Binary to Hexadecimal

Procedure:

1. Partition binary number into groups of 4.
2. Compute the decimal equivalent of each group.

Octal to Binary

Procedure:

Convert each octal digit to its 3-digit binary equivalent

Hexadecimal to Binary

Procedure:

Convert each hexadecimal digit to its 4-digit binary equivalent.

Octal to Hexadecimal or Hexadecimal to Octal

Procedure:

Convert first to either Binary or Decimal.

I got this information from our laboratory handout. We also had an intraclass quizcon. It was so much fun converting under time pressure. I hope that I will soon be able to convert without my handout:)
