Last value in FOR loops, using STEP and fractions, sometime results in unexpected values

• Platform: MEGA65, R6
• ROM Release: 920417
• Core Commit: aaf4542

Describe the bug
Using STEP with fractions in FOR loops can sometimes lead to unexpected results; e.g. the last value is completely off.

To Reproduce

Expected behavior
The last value should be 10, not 0. (The same example in BASIC v2 will not print 10, but 9.70000002 since the fractions are handled differently, I guess.)

Screenshots
See screenshot above.

Additional context
This is a bit sneaky since doing the same loop, but up to 4 instead of 10, works as expected. I guess the inner workings are much like those of BASIC v2, but it is better "hidden" from the user. In that case, it might not be expected to have the last value of 10. (But it should not be 0 at least... 😉)

[jwa1974]

The example above goes from 1 through 10, but if the loop was 1 through 100, the "10" would still be a 0, just to be clear.
