What are real constants in java?

"real" numbers, in any programming language, are actually approximations of what is called a "real number" in math. Basically, a number that can handle decimals - but unlike the actual real numbers, of limited precision. In Java, the "real" data types are float, and double. double has greater precision. A "constant" in Java is similar to a variable, but its value can't be changed after it has been assigned a value.

float and double are types of numbers that accept decimals. Consider them as numbers in scientific notation. double allows a larger range of numbers than float, and more significant digits. Usually you would use double, unless you have some special situation, like a large array of numbers, and you decide the extra precision is not necessary.
