January 23 2014

Hosts: Fr. Robert Ballecer, SJ and Shannon Morse

Welcome to Coding 101 - It's the TWiT show that gives YOU the knowledge to live in the wonderful world of the programmer. This week we are taking a look at binaries. You can also check out the transcript of the show here.

Ivory Tower: Binary

Binary is a base 2 system. With the total sum based on each binary value being either "on" or "off" (Which is why it's called "BINARY")

2-bit Binary Value

  • Each BIT can have 2 values - on or off - 1 or 0
  • Each Bit is worth the value of powers of 2, counting up from 0.
  • We count the values from right to left.
  • With two bits, that means the "first" bit can be worth either "1" (2(0)) or "0" while the second bit can be worth "2" (2(1)) or "0"
  • If we have a value of 00 = 0 :: 11 = 3 :: 10 = 2 :: 01 -1
  • If we have a n 8-bit value the maximum value will be (1+2+4+8+16+32+64+128) 255

Let's Break Down the process!

  • If I had a value like 10101010... what logic would I use to get to the DECIMAL value? (170)
  • I would create a "Total" Variable
  • I would look at each position, from left to right, giving each position a value of 0-7
  • If the value was "0" then I would skip to the next value.
  • If the value was "1", then I would raise 2 to the power of that position, then add that value to the "Total" Variable
  • Once I have no more values to calculate, I would report my total.
