WP 34S Modulo Bug

[Paul Dale]

I already fixed this bug -- circa twelve hours ago now. Walter doesn't touch the code. That's for me and Marcus. As for the numeric code, it is almost exclusively me.

Put bluntly, the first post was not a good bug report. It didn't say what answer was expected. It didn't include results from other calculators. It certainly didn't mention remainder. I might write a report that claims \(SIN(\frac{\pi}{12})\) should be \(\frac{\sqrt{3}-1}{\sqrt{2}^3}\) but I'm getting 0.2588, please fix. Should I begin recoding immediately?

Subsequent posts filled in all these details and then I acted. I don't jump to fix things instantly, I need to know that there really is a problem and what the proper fix should be. These functions are often subtle and the obvious fix won't work. If I'd had a 41C to hand, I might have acted faster, but I didn't.

Still, I'd say that a twenty four or so hour response time from the initial report to a committed fix is far better than you'll ever get from a commercially supported product. Remember that we're making no money from this firmware, it is a labour of love.
