You could simply use temp 256.
What is floor division in java.
The first argument is the number being divided.
The floor method rounds a number downwards to the nearest integer and returns the result.
Division there are two kinds of division in java integer and floating point they both use the operator to ensure you will get them confused.
Java int division is not quite the same as python s floor division.
Rounds towards negative infinity.
Java int division rounds towards zero.
Throw away the remainder and the result is 2.
Thus 7 3 is 2 with a remainder of 1.
If the argument is nan or an infinity or positive zero or negative zero.
The second argument is the divisor.

The java lang math floor returns the double value that is less than or equal to the argument and is equal to the nearest mathematical integer.
But 5 2 in java will give you 2 if that is what you re after.
This tutorial teaches java math class with examples.
Java math class provides useful methods for performing the math s operations like exponential logarithm roots and trigonometric equations too.
Java floor method the method floor gives the largest integer that is less than or equal to the argument.
It depends on whether the operands surrounding it are int long or float double which form is used.
Temp 256 is an integer by java s rules for integer arithmetic and using math floor on an integer is pointless.
If the argument value is already equal to a mathematical integer then the result is the same as the argument.
Java does integer division which basically is the same as regular real division but you throw away the remainder or fraction.
Using math floor is superfluous.
Why the author did this is impossible to answer without reading their mind.
Integer division can come in very handy.
String args use math floordiv to compute the floor of a division.
If the passed argument is an integer the value will not be rounded.
If the argument is integer then the result is integer.
Even if you don t see a use for it now it is used quite often.
Java math floor method floordiv and floormod use the math floor method to reduce numbers to the nearest lower integer.
