Question

Write a function called truncate. It is passed 2 parameters, a float f and an integer d. The function truncates f so that it has d digits to the right of the decimal point. For example:

>>> truncate(line_length((0,1), (1,0)), 3)

1.414

>>> truncate(circle_circumference(1), 1)

6.2

>>> truncate(circle_area(1), 4)

3.1415

Answer 1

I am using c# coding to solve above problem. the following code gives output as you want.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
class Program
{
public float Truncate(float f, int d)
{
/* local variable declaration */
float result;
result = f;
return result;
}

static void Main(string[] args)
{
float f, result;
int d;
Console.WriteLine("Enter a float value");
f = float.Parse(Console.ReadLine());
Console.WriteLine("Enter a integer value");
d = int.Parse(Console.ReadLine());

Program p = new Program();
result = p.Truncate(f, d);
string afterDecimalResult = Math.Round(result, d).ToString();
Console.WriteLine(afterDecimalResult);
Console.ReadLine();
}
}

}
