Do you have to retype often a calculation only because you fed in the numbers in the wrong order?
Star Calculator comes with two special buttons besides the usual −×/ for arithmetic operations. The dividing button
reverses the division and the subtracting button | reverses the subtraction. When dividing you won't have to resort to the 1/x inverse function or to power −1 before multiplying by the second number. When subtracting you won't have to change the sign before adding. This way more calculations can be performed on the go without having to retype or to apply mathematical workarounds.
Examples:
2.0
7.1 is the same as 7.1 / 2.0 = 3.55
4.9 | 8 is the same as 8 − 4.9 = 3.1
