decimal celciusDiv not working and being used as 0 when casted as int

Trying to convert from farenheit to celcius and it just isn't working and I'm not sure why exactly. i can't multiply by a decimal variable it seems so have to cast as int. It then seems to result in celciusDiv becoming 0 instead of 5.0m/9.0m. It's a logic error as well so it won't even tell me why it isn't working.

You're rounding celciusDiv to an int An integer is... an integer It cannot have any decimal places

Damn I just realised. Yeah I get you. In that case I'm not sure then how I would multiply by a decimal value

REPL Result: Success

var dec = 5m / 9m;
Console.WriteLine($"Decimal is {dec}");
var i = (int)dec;
Console.WriteLine($"Rounded it's {i}");

var dec = 5m / 9m;
Console.WriteLine($"Decimal is {dec}");
var i = (int)dec;
Console.WriteLine($"Rounded it's {i}");

Console Output

Decimal is 0.5555555555555555555555555556
Rounded it's 0

Decimal is 0.5555555555555555555555555556
Rounded it's 0

Make fahrenheit also a decimal

GraxonusOP•4mo ago

Yeah I see what you mean, that's my mistake.

Angius•4mo ago

And work only with decimals

In general or just with this file?

Well, wherever it makes sense Temperature, in general, can have decimal values So it should be represented as such If you're working with, dunno, warehouse management system, you can't have 1.8291 of a watermelon So integers make sense

Yeah I get you that was just a silly thing on my part. I need more sleep or something 🤣 Thanks much, though.
