I use my own calculators because so far:
Are both inaccurate (or just too cumbersome to make correct, not sure which).
That’s for Pi.
So I built a calculator for Industry, just putting finishing touches on taxes and fees with a partner of mine.
And I am looking forward to testing some of the Industry calculators as well.
But basically the point of this thread is to discuss the calculators. Why the two mentioned seem incorrect.
What industrial calculators do people use and find them to be accurate?
