Version 1.5.1

Small release to fix a bug in version 1.5. The bug was that undefined values weren't graphed properly (properly in this case being not at all) when the equation was entered in algebraic notation. Because of this bug, for example, sqrt(1-x^2) would appear as the top half of a circle like it should, except there would be two vertical lines on the sides. Version 1.5.1 fixes this bug.

Version 1.5

This new release includes a new feature that several people have requested: RPN input is now optional. Pressing A will open the system keyboard, where you can type in an equation using traditional algebraic notation.

In addition, if you have a New 3DS (or possibly a Circle Pad Pro, not sure if it's compatible) you can control the first two variable sliders ('a' and 'b') by moving the C-stick.

Version 1.4

I forgot to do a release for a long time. Anyway, here's the changes, in the order in which they were made:

• New icon (banner is still ugly though)
• (3DSX only) Added title/author info to SMDH
• Circle pad dead zone increased
• New fonts (this is the result of changing to a new text rendering library that uses a different font format)
• Default equation changed to the simpler y=sin(x)
• UI now makes use of gradients and has a shiny appearance

Version 1.3

Two main new features in this release. One is the alternate-function mode, which works like the 2nd key on many handheld calculators. Press Select to turn it on or off; pressing a button automatically turns it off, even if the button doesn't have an alternate function. The old function of the Select button, resetting the view, is still available as the alt-function for the "clear" button. There are also a few new functions available in this way, and there's room for many more which I'll consider adding if anyone suggests them.

The other new feature is the adjustable variable sliders. Basically, you can insert a variable into the equation, which you can adjust via a slider and see the changes in real time. You can also change the range of the slider; see the readme for information about how to do that.

Version 1.2

Small release here. Only new feature is that you can hold down B while in trace mode to snap to units. The exact unit it snaps to is the smallest power of 10 that makes sense to snap to, based on the current zoom level.

Thanks to videogame57 on gbatemp for suggesting this feature!

Version 1.1

The main new feature in this update is the multi-plot functionality. You can have up to four plots (you probably won't need more, and with four active it starts to slow down a bit so that's probably a good maximum) which you can switch between by pressing Up/Down on the D-pad. (They're all visible at once obviously; the switching is only for editing the equation or using the trace cursor.)

Also, I just realized there's a useless test screen in this version that I forgot to remove. It's not the kind of thing that could get in the way though, so I don't really see the harm in leaving it there until the next update. Just pretend it's an Easter egg and try to find it; it's not hard! :)

Another huge commit! Sorry!
