Square root only works with German numbers system

[rowanmoxie]

When coding the JSON framework for an arithmetic model, the square root function can only be calculated using the German numbers system. This means that **(0,5) must be used, as opposed to **(0.5). As the repo is English, and the calculations are otherwise returned with decimals instead of commas, this is inconsistent. When **(0.5) is applied, the program returns NaNs instead of number values.

Hi, thanks for raising this issue! I will try to fix it as soon as possible. However, I am maintaining this project, which is the result of a publication I worked on a few years ago, in parallel to my full-time job, so please don't expect it to be fixed right away.
