Question

Convert the following numbers from binary to decimal:

101.101001   

0.000101

1.0

Convert the following numbers from decimal to binary:

12.28125

0.0234375

0.7

***If you could show some of the work so I can understand how to do this better, that would be greatly appreciated.

Answer 1

import java.util.Scanner;
public class example {


public static void main(String[] args) {
  
Scanner sc = new Scanner( System.in );
System.out.println("enter binary: ");

float bnum=sc.nextFloat();
float bnry=bnum;
  
int dec = 0;
int pow = 0;

while(true){

if(bnry == 0){

break;

} else {

float tmpr = bnry%10;
dec += tmpr*Math.pow(2, pow);
bnry = bnry/10;
pow++;

}
}
System.out.println("binary is:="+bnry+" decimal is:="+dec); ;
}

}
ouput:
enter binary:
01
binary is:=0.0 decimal is:=1
enter binary:
1.0
binary is:=0.0 decimal is:=1




import java.util.Scanner;
public class example {


public static void main(String[] args) {
  
   int i = 12;

String num = Integer.toBinaryString(i);
  
System.out.println("decimal to binary:");
System.out.println("val is:" + i + " is :" +num);
  
}

}
output:
decimal to binary:
val is:12 is :1100
