This question already has an answer here:
How can I divide two integers to get a double?
5 answers
My code is here
if (dUIAnswer == "yes" || dUIAnswer == "ya")
{
quote += (25 / 100) * quote;
}
if (coverageType == "full coverage")
quote += (50 / 100) * quote; ;
return quote;
I am basically trying to increase the value "quote" by 25% of itself if the user has a DUI. Please give me a simple solution of code that is possible.

25 / 100 does integer division so the result is 0 (of type int). Make them decimal i.e. 25.0M / 100.0M or better yet:
quote *= 1.25M;

The problem is: the result of 25 / 100 or 50 / 100 is 0, in C# and similar languages (C, C++, ...).
Why?
In C#, when you divide an integer (int, long, etc.) by an integer, the decimal section is truncated - 0.25 becomes 0.
So, there are some solutions:
1) Simply write 0.25 (or 0.5) in your code:
if (dUIAnswer == "yes" || dUIAnswer == "ya")
{
quote += 0.25 * quote;
}
if (coverageType == "full coverage")
quote += 0.5 * quote; ;
return quote;
2) Convert one of the numebrs to double or to float, by attaching it the postfix D (for double) or F (for float), or by adding to it an .0 at the end (which does it a double), or by casting it with (<type>):
if (dUIAnswer == "yes" || dUIAnswer == "ya")
{
quote += (25.0 / 100D) * quote;
}
if (coverageType == "full coverage")
quote += ((float)50 / 100) * quote; ;
return quote;
(You also can convert it to decimal, explicitly or by attaching M as postfix).

To add 25% to the cyrrent value so it will become 125% of the current value, so multipy it by 1.25 (125%):
if (dUIAnswer == "yes" || dUIAnswer == "ya")
quote *= 1.25M;
if (coverageType == "full coverage")
quote *= 1.5M;

"quote" is a decimal variable, so needs multiplying by 1.25M & 1.5M otherwise you get a compile time error (CS0019 Operator '*=' cannot be applied to operands of type 'decimal' and 'double')
