E2188 Expression Syntax error [borland c++]

[oritemusic]

I'm getting an error at the red line saying E2188 Expression Syntax. Any ideas how to fix it ?
I am trying to use the function for square root calculation

{long int rootsie, n, m;
m = StrToInt(Edit1->Text);
n = StrToInt(Edit2->Text);
rootsie= double sqrt(double m);
}

You need brackets to typecast.

rootsie=(long int)sqrt((double)m);

PS: long int is usually the same as int (depends what platform you are on).

Still doesn't work, says Call to undefined function 'sqrt'

 

[PurplePoot]

Presumably you are outside its namespace.

Oh, actually my mistake was simpler, I just forgot to include the math library
