this might be a silly question but what does sqrt do?

is that a trick question?

sqrt(9);

this returns 3 - the square route?

aaaah it was a silly question.

didnt now it was typed like that on the computer.

Root, not route

Actually, it goes like this:

_asm {    FLD     var    FSQRT    FSTP    var} 

If you do that simple asm manually and don''t FSTP until later, it''s essentially free!
