The 'fixnump' error is what you get when something that wants an integer argument is fed something else, like a real number, instead. That suggests something like a (repeat) function, but not any of the functions in that excerpt.
But maybe that excerpt is changing the variety of number of a numerical variable that it works on, to pass the wrong kind to something further along. Without digging deeply into the overall routine, I wonder whether this:
(set (var2 "b") (+ (ev2 "b0") 0.0625))
should be this instead:
(set (var2 "b0") (+ (ev2 "b0") 0.0625))
If the (var2 "b") variable is a number of bays, that's likely to be fed to something like (repeat), in which case if you've added decimal values to it, you'll get complaints. But I suspect it's (var2 "b0") that you want to change until it comes within range.
And if that's the case, I think you need a (while) instead of that (if), so it keeps changing it until it comes within range -- as you have it, I think it will change it only once.

I hadn't dug very deeply into the overall routine, but was just assuming that the variable with (var2 "b") might be used for a number of bays or something. But it looks like its value, taken by (ev2 "b"), is used only as part of a distance sum for (polar) functions, so it wouldn't matter if it was a real number rather than an integer.
But I still think
(set (var2 "b") (+ (ev2 "b0") 0.0625))
might want to be
(set (var2 "b0") (+ (ev2 "b0") 0.0625))
instead.
Don't you want to increase the existing value with the 0 in its variable name by 1/16 from its current value, until it gets big enough? The code with the red b in it increases the variable without the 0 to 1/16 more than the value of the variable with the 0. If it needs to do it more than once, it will keep increasing it to the same thing over and over, because what it's adding 1/16 to hasn't been changed in the meantime. So it will never get to the target value and stop the loop.
But to answer your question about adding decimals causing issues, it's only if what you're adding them to is going to need to be an integer. If I had been correct in assuming that the one with without the 0 was something like a number of bays, it could have been used in something like a (repeat) function. But (repeat) can't repeat something 6.0625 times -- it needs an integer for the number-of-times argument, and if you give it a real number instead, you get just the error message that you described. However, that's all moot in this case, if it's not used as I was assuming when I hadn't looked deeply enough.
