Mage plugin fails with long decimals

[doloopo]

Environment

Windows build number: Windows 10 1909 (build 18363.836)
PowerToys version: v0.18.0
PowerToy module for which you are reporting the bug (if applicable): PowerToys Run

Steps to reproduce

Just enter any decimal in PowerToys Run, and add more and more "0" at the end, such as:
0.100000000000000000000, 0.200000000000000000000000

Expected behavior & Actual behavior

The result should be 0.1 when I type 0.100000000000000000000, but not 0.007766279631452241.

I know it might be the problem with the datatype float or double, but I cannot really stand the result. I think the datatype should be more ACCURATE.

calculations are done by mage right now. doubtful little we can do until #2265

@MindSkyHost what is the real world scenario where you'd do this type of calculation here

It's not only about the problem I mentioned. There's also problems with the meaningful calculations such as that 1 - 9.0 / 10 I want to get the result 0.1 but not 0.09999999999999998. I'm afraid that when the numbers are different the glitches will become big problems.

Also, the glitches will not happend in Listary Beta 6.0.5.16 (the version I'm using).
