EDIT: ( Correct result should be close to .131652)
Windows Calculator: 0,00228463462331349894308299181234

When in Radian mode, Windows calculator (Windows 10 version) gives

0.13165249758739585347152645740972

You were in Degree mode when you did your calculation.

Yes, I was in DEG mode on the 15c as well but inadvertently it was also in "C" mode which meant the calculation was performed in RAD despite seemingly being in DEG. This confused me.

But it is also interesting to compare the precision of the different calculators so I don't mind at all the posts in this thread.
