Why the author did this is impossible to answer without reading their mind. But 5 2 in java will give you 2 if that is what you re after. The java lang math floor double a returns the largest closest to positive infinity double value that is less than or equal to the argument and is equal to a mathematical integer. If the argument is nan or an infinity or positive zero or negative zero.
