Decimal mode - multiple operations are not calculated in typical order of operations

Hi Anthony,

The decimal mode of this calculator does not follow typical order of operations when using compounding operations.

To reproduce:
Compare the following steps between HexaCalc and the iOS calculator (or other system calc such as Windows calculator):

  • 60 - 0.1 * 60
    or
  • 60 - 60 * 0.1

it seems the calculator ends the calculation at each state after a second input.
this means it isn't really suitable as a general purpose decimal calculator, which is a drawback especially on iPad, which still doesn't have a native iOS calculator.

Happy holidays,

Hello Wes,

Sorry for the late response to this! I completely missed this post.

You are for sure right, the calculator is only designed to compute a calculation of two inputs, so when you click a second operation before pressing equals, it will compute the result of the first calculation, such as (60 - 0.1 = 59.9 * 60 = 3954).

This is something that I want to address by adding bracket operators or some kind of scientific mode that will allow you to enter calculations of any size, such as (60 - (0.1 * 60)) = (60 - 6) = 54. This will let you enforce the order of operations that you expect.

I will work on this new feature when I get some time, but it is high on the list of things I want to add to the calculator!

Thanks for the request! I will let you know once I add it
