Definition and Usage. The float keyword is a data type that can store fractional numbers from 3.4e−038 to 3.4e+038. Note that you should end the value with an "f":
- Let's see a simple example to display float type variable. public class FloatExample1 { public static void main(String[] args) { float num1=5.5f; float num2=5f; System.out.println("num1: "+num1); System.out.println("num2: "+num2); } }
- In this example, we provide integer value to float variable. Here, compiler implicitly typecast integer to float and display the corresponding value in fractional form.
- In this example, we provide bigger decimal value. public class FloatExample3 { public static void main(String[] args) { float num1=581216732.323433f; float num2=7.83684987683688f; System.out.println("num1: "+num1); System.out.println("num2: "+num2); } }
- In this example, we provide float value to the decimal variable. public class FloatExample4 { public static void main(String[] args) { float num=56.34; System.out.println("num1: "+num); } }
The Float class wraps a value of primitive type float in an object. An object of type Float contains a single field whose type is float . In addition, this class provides several methods for converting a float to a String and a String to a float, as well as other constants and methods useful when dealing with a float.

Floating-point numbers are those numbers that require “fractional precision” i.e. the numbers that can be in the fraction. There are a lot of mathematical calculations where we can use Floating-Point types like finding square root or cube root of any number, finding roots of quadratic equation, dealing with trigonometries like sin and cos, and so o...
Float is a single-precision value that has a width of 32 bits in storage. On some processors, this single precision is faster and takes less size when compared to the double-precision. This is arguable as on some modern processors, double-precision is faster than the single-precision. As far as Java variables are concerned, we can use float while i...
In this tutorial, we have learned about floating-point types and the Java float. The comparison with Java double and the major differences were provided. Each section included simple programming examples along with frequently-asked questions. There are a lot of different ways and rules for initializing a float variable in Java and we discussed thos...
float: The float data type is a single-precision 32-bit IEEE 754 floating point. Its range of values is beyond the scope of this discussion, but is specified in the Floating-Point Types, Formats, and Values section of the Java Language Specification.
Java float keyword is used to define one of the eight primitive datatypes supported by Java. It provides means to create float type variables which can accept a float value. Following are the characteristics of a float data type.
Oct 30, 2023 · In Java, the float keyword identifies a data type that can hold decimal numbers, created with the float keyword before the variable name, and must have an ‘f’ after the value, such as float num = 1.11f. The ‘f’ after the value tells Java that the value is a float.
