You just need to cast at least one of the operands to a float:
float z = (float) x / y;
or
float z = x / (float) y;
or (unnecessary)
float z = (float) x / (float) y;

Convert int to float - GeeksforGeeks
March 26, 2024 - Converting an integer to a floating-point number involves changing the data type of the variable from int to float, allowing decimal values. This conversion is useful when performing arithmetic operations that result in fractional values or when working with numerical data that requires precision beyond whole numbers.
How do I cast my int to float?
To cast a value, you put the destination type in brackets before the value or variable you want to cast, for example (float)x would cast x to a float. However, I assume you're talking about L and S here, in which case just casting won't do you any good since you've declared them as int. They won't be able to hold any decimal places, so casting them to a float would just give you the same wrong number but as a float instead of an int. More on reddit.com

The second example is part of the Java language and is called type-casting. It is can only be used to convert numeric and char types to integer. So it is fine if the data type is one of the following char short long float double but will not work with strings. More on forum.processing.org

[1] initial value as a float, and then [2] convert it to an integer, [3] multiply by 1000 If you follow these steps exactly, you will lose information. Converting a float to an int drops the fraction component, so you have to do step 3 before step 2. More on reddit.com

In this case, it will print 56.0 since float can accurately represent integer values without any loss of precision. ... The above code serves as a clear example of how Java handles implicit type casting, making it convenient for developers to work with different data types in their programs.

April 21, 2026 - No IEEE 754 floating-point operation provided by Java can distinguish between two NaN values of the same type with different bit patterns. Distinct values of NaN are only distinguishable by use of the Float.floatToRawIntBits method. In all other cases, let s, e, and m be three values that can be computed from the argument: int s = ((bits >> 31) == 0) ?

August 7, 2023 - The int and float each take 4 bytes of memory. The int holds a whole number, and the float holds a floating-point number. Assignment of int to float is done automatically by JVM.

Using Math.round() will round the float to the nearest integer.

Actually, there are different ways to downcast float to int, depending on the result you want to achieve:
(for int i, float f)
round (the closest integer to given float)
i = Math.round(f); f = 2.0 -> i = 2 ; f = 2.22 -> i = 2 ; f = 2.68 -> i = 3 f = -2.0 -> i = -2 ; f = -2.22 -> i = -2 ; f = -2.68 -> i = -3note: this is, by contract, equal to
(int) Math.floor(f + 0.5f)truncate (i.e. drop everything after the decimal dot)
i = (int) f; f = 2.0 -> i = 2 ; f = 2.22 -> i = 2 ; f = 2.68 -> i = 2 f = -2.0 -> i = -2 ; f = -2.22 -> i = -2 ; f = -2.68 -> i = -2ceil/floor (an integer always bigger/smaller than a given value if it has any fractional part)
i = (int) Math.ceil(f); f = 2.0 -> i = 2 ; f = 2.22 -> i = 3 ; f = 2.68 -> i = 3 f = -2.0 -> i = -2 ; f = -2.22 -> i = -2 ; f = -2.68 -> i = -2 i = (int) Math.floor(f); f = 2.0 -> i = 2 ; f = 2.22 -> i = 2 ; f = 2.68 -> i = 2 f = -2.0 -> i = -2 ; f = -2.22 -> i = -3 ; f = -2.68 -> i = -3
For rounding positive values, you can also just use (int)(f + 0.5), which works exactly as Math.Round in those cases (as per doc).
You can also use Math.rint(f) to do the rounding to the nearest even integer; it's arguably useful if you expect to deal with a lot of floats with fractional part strictly equal to .5 (note the possible IEEE rounding issues), and want to keep the average of the set in place; you'll introduce another bias, where even numbers will be more common than odd, though.
