I am trying to compare the floating type value in my code like

if sum=1.0 then
Code statements true
else
code statements false
end if
but what happened is sometimes even if the sum is 1.0 then also
it goes to else block of code . How do I solve this ?

Use TryParse and implement the code.

Double sums;
sums = 1.0;
string s;
if (sums == 1.0)
{
s = "welcome";
}
else
{
s = "test";
}
MessageBox.Show(s);

Go through http://www.vb-helper.com/howto_net_compare_float.html[^].
Use something like CStr(Math.Abs(sum - 0) < 0.00001).
