Easy. Just continue the pattern from the left side of the dot:
1*8^1 + 0*8^0 + 3*8^-1 + 4*8^-2 = 8.4375
Question
In octal, I'm typing the number 10.34 into a couple of different online converters to convert them to decimal, and they say that it's an invalid octal number.
I know that the octal number 10 can be worked out by
1x8^1 + 1x8^0 = 8
But is it possible to workout the right side of the radix.
Solution
Easy. Just continue the pattern from the left side of the dot:
1*8^1 + 0*8^0 + 3*8^-1 + 4*8^-2 = 8.4375
