Doubles take up twice the amount of memory as floats do (hence the name) but as a result they are more precise and can represent a wider range of values. Memory space doesn’t matter as much as it used to so for most use cases, doubles are just fine. In certain applications though where speed and performance is a higher priority than accuracy, such as graphics calculations for video games, using floats instead of doubles may be preferable.

r/learnprogramming on Reddit: When should I use double and when should I use float for Java?

January 6, 2024 -

I am learning Java, and am confuse on when to choose double or float for my real numbers or int. It feels like, it doesn’t matter because from my limited experience (with Java) both of them deliver the same results, but I don’t want to go further down the learning curve with Java and have a bad habit of using either messing up my code, and not having a clue as to why. So, when should you use float and double?

Doubles take up twice the amount of memory as floats do (hence the name) but as a result they are more precise and can represent a wider range of values. Memory space doesn’t matter as much as it used to so for most use cases, doubles are just fine. In certain applications though where speed and performance is a higher priority than accuracy, such as graphics calculations for video games, using floats instead of doubles may be preferable.

If you aren't sure, use a double. A double is accurate to about 15 digits while a float is only accurate to 7. If you're storing lots of numbers, you might need to use floats to fit everything in memory but that's not an issue until you're dealing with millions of numbers.

floating point - What is float in Java? - Stack Overflow

In Java, when you type a decimal number as 3.6, its interpreted as a double. double is 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).

For more explanation, see the primitive data types definition of the Java tutorial.

Make it

float b= 3.6f;

A floating-point literal is of type float if it is suffixed with an ASCII letter F or f; otherwise its type is double and it can optionally be suffixed with an ASCII letter D or d

Java double vs float: What's the difference?

If all of the values fall within the range of a float, it makes sense to use the smaller Java data type in this situation, otherwise the array elements needlessly consume memory. Data precision can be a problem with double and float types because binary numbers don’t always convert cleanly to decimals. For example, the following program prints out 11.3999 as the sum of 5.6 + 5.8:
