Question

I have a variable which contain the textfield value. I want to multiply that x value with a decimal number like 0.013. But after multiplication I got as answer 0.
It takes the decimal value as 0. What is the reason?

Answer 1

In a comment, the OP notes

If i use 4/3 then it only takes answer as 1

This suggests that the problem is in how the value is initialized: 4/3 is integer division, returning the int value 1. The solution is to be sure that the calculations are actually dealing with floats, start to finish, by using float literals, e.g., replacing 4/3 with 4.0/3.0
