A test of the pressed button should be performed.
behind it is the calculation ....
case RadioGroup1.ItemIndex of 0:f:=cos(x); 1:f:=sqr(x); 2:f:=exp(x); end; if f>y then q:=f else q:=y if z>q then q:=z
Produces an error in the string
if f>y then q:=f else q:=y Variable f might not have been initialized
What is the problem - I can not understand, can someone tell me.
all variables of type
