The most complete calculator for everyone.
PCalc 4.5.3 on 10.8 bug
This is really a great app, but I'm using 10.8.5 Mountain Lion, yes I know it's an old os, and there's a bug I noticed.
About a third of the time opening the app, the number screen comes up blank. Not with a zero or anything else, just blank.
After a few more times of closing then opening, it works fine again, finally showing numbers. Is this just a Mountain Lion bug,
or is anyone else having this problem? Oh well, it actually works sometime, just wondered if anyone else has experienced this too.
I'm using version 4.5.3.
ALL TIME GREATEST CALCULATOR
If you’re an engineer, programmer, scientist, number lover, or calculator fanatic then welcome home. This app is for you. You will be giddy with happiness from the functionality and ui. You will experience joy you never thought a calculator could possibly bring you. It can even calculate the ultimate number.
-To the devs, thank you so much. I’m estatic that I found this app. It’s like my years of frustrated search has concluded. A search I didn’t realize existed until I found this. I never have to switch calculators or get frustrated from limits.
