What does float mean in java

float in Java means "floating", which represents a floating-point data type. It allocates 4 bytes of memory and occupies 32 bits, ranging from "10^-38" to "10^38" ” and “-10^38” to “-10^-38”. Data defined as float type must have "f" or "F" at the end.

Java is an object-oriented language with eight data types, namely: byte, short, int, long, float, double, char, boolean. What I will tell you next is the float data type in Java.

float in Java represents a floating point data type

Floating point types include:

(1)float type The memory is allocated 4 bytes, occupying 32 bits, ranging from 10^-38 to 10^38 and -10^38 to -10^-38

For example float x=123.456f, y=2e20f; Note The data defined by float type must have "f" or "F" at the end, in order to distinguish it from double

(2) Double type The memory is allocated 8 bytes, ranging from 10^-308 to 10^308 and -10^-308 to -10^-308

Example double x=1234567.98,y=8980.09d; There may or may not be "d" at the end

Java’s eight basic data types are:

1) four integer types (byte, short, int, long)

2) two Floating point type (float, double)

3) A character type (char)

4) A Boolean type (boolean)
