Here's Part 2.

This is largely due to the fact that floats cannot store base ten fractions precisely. The mixup rounds the value so that the small cumulative error resets. A different fixup would be to convert the initial value to units of pennies instead of dollars.

Thank you for explaining. So is this something that can be fixed by NI or just a quark in programming? I remember there was something similar last year with the equal function but that seems to have been fixed.
