Difference between sqrt and sqr ?

[NeilTrain]

Hello all,

I am attempting to convert an algorithm from Pascal to C#, for the most part it went pretty easily, until I came across "sqrt", which I assumed was Square Root, then soon after was a "sqr" which I assume is something else?

Can anyone explain this one to me?

sqrt = square root.
sqr = square.

sqrt(9) = 3, while sqr(9) = 81.

how silly of me, that was an easy one, should have turned my brain on and figured that.

Thanks anyways though.
