Conversion from float to double:

In this tutorial we will learn how to convert a float type value to double type value.

Description:

This program will take a float value from console and provides a conversion to double type data. The line float myfloat = Float.parseFloat(buffreader.readLine()); reads the float type data from console. The line double mydouble = (double)(myfloat); converts the myfloat float type value to mydouble double type value.

Code:

import java.io.*;

class floattodouble {
public static void main(String[] args) {
try {
// Reads the value from console
BufferedReader buffreader = new BufferedReader(new InputStreamReader(System.in));
System.out.println("---Data Conversion from float type to double type---");
System.out.println("Enter float type value: ");
// Read float type data
float myfloat = Float.parseFloat(buffreader.readLine());
// Convert float type data to double type
double mydouble = (double)(myfloat);
System.out.println("Converted value from float type to double type is : " + mydouble);
} 
catch (Exception e) {
System.out.println(" Error " + e);
}
}
}
