Missing automatic parentheses around a fraction or when entering its denominator #98

Closed mmaxs closed 3 years ago

mmaxs commented 3 years ago

μMath+ v2.20.0.

Two expressions that look the same are evaluated differently: IMG_20201107_223430

The first expression is entered by using the #•# template first with a tool button, wherein the left placeholder is filled in with 2/2 keystroke, and the right one with 2. The second expression is enered as a straight keystroke 2/2*2. According to its view on the worksheet it should be evaluated as = 2. Actualy it is treated as 2/(2*2)=0.5

Here is another example (values with units). Here, km/hr is intuitively considered a unit of measure for 12, not a specifically entered fraction 12 km / 1 hr, so the first operand of multiplication is expected to be implicitly enclosed in parentheses. IMG_20201107_231210

Thank you for a great app!

Hi @mmaxs I fixed the first problem. Now, the parenthesis will be automatically added into the right placeholder. If you like to test it, please install the latest nightly build from here: https://github.com/mkulesh/microMathematics/raw/autobuild/autobuild/microMathematics-v2.20.1-debug.apk This build is not signed. Depending on Android version you may need to uninstall the previous signed version. For the second example (values with units), I need some more time to investigate it.

Hi, Mikhail. I have been using it with a couple of worksheets for a while and have found no new problems.
