Converting string to numbers

Posted by absm on April 10, 2001 at 11:30 AM

Could someone please test with the following command line
arguments 4.5 and 87.2
Please show how you did it if it worked ?
When these are used as command line arguments the output
is as follows:

a+b = 91.7
a-b = -82.7
a*b = 392.4
a/b = 0.0516055
a%b = 4.5

public class ValueOfDemo {
public static void main(String[] args) {

//this program requires two arguments on the command line
if (args.length == 2) {

//convert strings to numbers
float a = Float.valueOf(args[0]).floatValue();
float b = Float.valueOf(args[1]).floatValue();

//do some arithmetic
System.out.println("a + b = " + (a + b) );
System.out.println("a - b = " + (a - b) );
System.out.println("a * b = " + (a * b) );
System.out.println("a / b = " + (a / b) );
System.out.println("a % b = " + (a % b) );
} else {
System.out.println("This program requires two command-line arguments.");
}
}
}
