This is a Fahrenheit calculation program below

bool flag;
flaot tc,tg;

flag=float.TryParse(txtbox1.Text,out tc);
if(falg==false)
{
messagebox.show("Invalid Entry");
}
txtbox1.Focus();
return;
tg=(5/9)*(tc-32);
txtbox2.Text=tg.tostring();

when i run this program i am getting the result as "0"(i had taken tc=123 as a value)

NOTE: But If I Use Double Instead Of Float I Am Getting The Answer.Why Cant Float Get Answer instead Of "0".

(5/9) is int and (tc-32) is float
This is due to implicit conversion from float to int

For example:

You will get value if you calculate as follows:
