I’m a boat rigger and this calculator has made my job easier.
Can’t work without, I’m constantly having to do mathematical calculations and a mistake can be costly! This app saves me time and money.
Still the same as doing fractions by hand but much easier on the brain. Great app!
Awesome app. Very handy.
Use it all the time very helpful
Didn’t work after update. Reinstated, now it works. Best fractions calculator I know of. 🙂 Beauty and functionality wrapped up in one. Great update, I can now do mixed equations of decimals and fractions and receive both decimal and fraction answers. Now I also receive mixed answers even when only doing unmixed equations. Beautiful Update. It’s good to know this update, will be the last time I’ll have to pay for it. Thank you 😊 "Would be nice if it followed OOO rules, also known as 'PEMDA’. It doesn’t require extra keys.” Maybe if there was a way to turn it off and on?
Very easy to use
To make this the ULTIMATE fraction calculator it needs to have user adjustable fractional resolution. By this mean user should have the option to have the calculator ROUND the result to the nearest fraction specified by the user: e.g., 1/16, 1/32, 1/64, 1/128… etc. Results like “258/10000000” are of no practical value. For me at least, this feature (one I would be willing tp PAY for) would make this calculator an indispensable daily use tool. Please consider it!!
Happy
Simplifies Measurements without Conversions! Been using it a long time. Sure makes life a little simpler and saves time.
途中式まで表示されるのがありがたいです 約分だけでなく分数同士の四則演算ができたりなにかと便利です
分数の宿題をチェックするのにとても重宝します。普通の電卓だと小数になってしまうので。
