Why is Sololearn rounding up numbers?

Question

I was writing some code to solve a challenge and it's crucial to have the double variable with its decimal place but when i run the code it gives me only the integer without the decimal places, I didn't ask to round up but it still doing it. For example i need the Math.Ceiling(31/7), it gaved me 4 instead of 5. (31/7 = 4.3 and the ceiling is 5)

Answer 1

AJ #Learn With Me 👨‍💻 correction in your statement, it should be
"Ceiling method returns nearest whole number GREATER THAN THE ARGUMENT PASSED so if there is value 4.3, Ceiling method will give 5.0"

Answer 2

Pepe like I said if you do
`double z = 31.0/7.0`
that will give you a double. Dividing integers by integers gives integers in C#.

Answer 3

The Math.Ceiling method returns the smallest integral value greater than equal to the argument passed
https://docs.microsoft.com/en-us/dotnet/api/system.math.ceiling?view=net-5.0#System_Math_Ceiling_System_Double_

Don't use Math.Ceiling method if you don't want int value. Just use 31.0/7.0.

Answer 4

Oh ok i see thank you both of you. 😀

Answer 5

Nvm I didn't say anything, the value i wanted was 5 not 4.3, sorry, i didn't write it correctly.

Answer 6

Pepe

Ceiling method returns nearest whole number so if there is value 4.3, Ceiling method will give 5.0.

if 4.1 then 5.0
if 4.8 then 5.0

Answer 7

Well Yes but my issue was when i put in a variable it will still give me a round up number. Like "double z = 31/7;" it will give 4 instead of 4.3 making not usable for Math.Ceiling because it uses the value of 4 instead of 4.3 and the ceiling of that 4 is 4.

Answer 8

Pepe You have to do like this to get fractional value.

double x = (double) 31 / 7;
