What is the use of float in Java program.

Answer 1

In Java, when you type a decimal number as 3.6, its interpreted as a double. doubleis a 64-bit precision IEEE 754 floating point, while floatis a 32-bit precision IEEE 754 floating point. As a float is less precise than a double, the conversion cannot be performed implicitly.

If you want to create a float, you should end your number with f (i.e.: 3.6f).
float a = 3.6f;
