it is the same as an int, String, or any of the others:
float myVar = 5.7f;
If you try to assign a decimal number you must place an "f" at the end, otherwise Java will assume you are trying to assign a double.

∙ 13y agofloat is a primitive datatype in java that is used to hold numeric values that contain decimal places.
Ex: float f = 10;
The above is an example declaration of a float variable. They can be used inall arithmetic operations like addition, subtraction, multiplication, division etc.
It uses 32 bits and there is as such no minimum or maximum value it can take. The value that a float can hold is larger than all possible numeric values that we can use in our systems (in most cases)

∙ 11y agoPerhaps you got an error message about a possible loss of precision?
The following will generate an error:
float f;
double d = 5.0;
f = d; // Here, there may be a loss of precision. The Java compiler will protest.
To solve this, tell Java that you (the programmer) know what you are doing, by using an explicit cast:
float f;
double d = 5.0;
f = (float) d; // Here, "d" is explicitly converted to type "float"

How do you declare many float variables in java?
You can declare them one by one. However, if you want to store lots of related data, you may want to consider using an array, where you use a single variable name (for example) for 1000 different items, and a number called an index to access the individual items.
