Geocache Description:


Binary (meaning 'two') is the ones and zeros that computers use.The reason for this, is there are only two states an electrical circuit can be in. Known as on and off or 1 and 0, 1 for on and 0 for off. By grouping 1's and 0's together, a computer, or electrical circuit can create letters numbers and 'True' or 'False.
Every bit of info in a computer has a binary code assigned to it and the computer knows these, for example, the letter 'A' converts to '01000001' in binary. Converting Binary Numbers to Decimal Numbers is quite simple.
Converting Binary to Decimal works by using a place value system. Let's take the Binary 10010011:
First we go from right to left (starting with one) and double it till we reach the end:

1
0
0
1
0
0
1
1
(128)
(64)
(32)
(16)
(8)
(4)
(2)
(1)

Now, if the value (in binary) is 1, then that is true, and the number assigned should be added to our total. If it is 0 then that is false and the number assigned should NOT be added to our total so from the above, we get:

1
0
0
1
0
0
1
1
True
False
False
True
False
False
True
True
+128
0
0
+16
0
0
+2
+1

These are all added together. Once the numbers have been added we get 10010011 = 147. So basically, all we do is add all the true numbers together.

Solve the following to get the cache coordinates:
S 11101 111000.101001 E 11110 111001.110110011
