Question

I want to summation in java.

So,

For example,

1.123 + 1.123E-4 = 0.0123411234

So, How can i processing “E” in java?

Answer 1

You mean something like this?

String a = "1.123";
String b = "1.123E-4";

double d1 = Double.valueOf(a);
double d2 = Double.valueOf(b);

System.out.println("sum = " + (d1 + d2));

Double’s valueOf() method can parse te E notation for you.

And actually, the result is: 1.1231123
