Basic C# question
using System;
namespace DecimalPart
{
internal class Program
{
static void Main(string[] args)
{
string number = Console.ReadLine();
double number2 = Convert.ToDouble(number);
double number3 = Math.Floor(number2);
double number4 = Math.Round(number2-number3,6);
Console.WriteLine($"Decimal part = {number4}");
}
}
this is my input:
13.62001
this is output that i should get:
Decimal part = 0.620010
how do i get 6 digits behind even when there is no 6 digits for example 26.389 and i want to get 0.389000?
This is what I'm getting:
Decimal part = 0.62001

Standard numeric format strings - .NET
In this article, learn to use standard numeric format strings to format common numeric types into text representations in .NET.
{number4} is implicitly telling the program to convert number4 to a string, and there are many ways to do that
the default is what you're getting, so you have to specify that you want 6 digits after the decimal pointi did that Math.Round(number2-number3,6); that six behind
oops, wrong section
Standard numeric format strings - .NET
In this article, learn to use standard numeric format strings to format common numeric types into text representations in .NET.
but, mathematically, is there a difference between 13.62001 and 13.620010?
well its more like i have to do that for my homework
i understand
but stick with me
as far as numbers go, is there a difference?
no
and
double is a numeric type
so it just stores the numeric value
passing 6 to Math.Round() just tells it how many digits to round to
what you want is to display a certain number of digits
and that's done by the format specifierok im going to check the link and see if i can come up with a solution
Console.WriteLine($"Decimal part = {number4:F6}"); change last line to this and it's working
there ya go
// Use a custom format string "0.000000" to ensure 6 decimal places.
Console.WriteLine($"Decimal part = {number4.ToString("0.000000")}");
