Incorrect result of root function evaluation

[faiwer]

Hello. Please look at next code:

mea.eval('root(4-(2-1)^2)'); // 3
mea.eval('root(4-1^2)'); // 1.732050807568877
mea.eval('(4-(2-1)^2)^.5'); // 1.732050807568877

Took me years but I did it! Solved in latest commit and published

mea.eval('root(4-(2-1)^2)'); // returns 1.73
mea.eval('root(4-1^2)'); // 1.732050807568877
mea.eval('(4-(2-1)^2)^.5'); // 1.732050807568877
