It is such an uncommon situation outside of maths class. We don't often need to refer to individual digits out of context of the whole number. It is hard for me to imagine a situation in which you would actually need to do this.
Given a number like 29034.4058032 You could say "There is a 3 in the millionths column" or "the sixth number after the decimal point is 3".
If you were just reading the number you don't need this: "twenty-nine thousand (and), thirty four point four zero five eight zero three two" It would almost always be easier to refer to the whole number, rather than to just one digit.
I've found the error in the code, and it's only a little one. On line 383 the constant should be 29034.4058052 and not 29034.4058032. Isn't it amazing that such a small mistake could cause the rocket to explode!?
