The keyboard issue in cupcake has been fixed in this version. Further cupcake support will come in the future version.
And the % button in the screen keypad has been removed. People always complain about 100-25% doesn’t equals 75%, while handyCalc take 25% as 0.25 (there is no data type for percentage in the core). The logic is confusing, so I do not recommend to use it. But you can still type % in your hardware keyboard to use it.

How will one use handy calc on devices without any such thing as hardware keybord?
The soft keyboard toggles between a few screens. The screenshot above is just the standard numbers and functions, the “up-arrow” will switch to scientific functions.
Alternatively, you can do a “swipe” motion on the onscreen keyboard (works left-to-right and reverse) to toggle between the different keyboard types. The QWERTY keyboard appears only with the swipe motion toggles.
Hi,
I can’t find Handycalc on the market. Is it a paid app now?
The newest version I can find (on softpedia I think) is 0.33. Help!
(Thanks, btw, for this app. I miss it already, as I’ve just received a replacement phone…)
Strange, it just appeared on my phone’s market. Not sure why.
I seem to have a problem with solving equations in the latest version. I enter
x+y=4
3x+y=10
When I press solve equations about x,y I get
x=2
y=4
which is obviously incorrect (see the first equation)
The correct solution is x=3, y=1, which seems to bear no relation to the calculated solution…
I carried HP business calculators for years, and as amazing as Handycalc is, one of the things I miss most about trying to make do with Handycalc are its lack of percentage functions… not just a percentage key.
For example, HP 19B and 12C calculators let us quickly calculate:
Percent Change
Percent of Total
Markup on Cost
Markup on Price
Sigh.
