Math round can be used to round a float value to int.

Java float to int floor.

A simple program that converts java float to int with rounding. By the way you must remember that type casting just get rid of anything after the decimal point they don t perform any rounding or flooring. Convert float to int with rounding. If the argument is nan or an infinity or positive zero or negative zero then the result is the same as the argument.

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. Returns the smallest of the two arguments. Double float int long. It returns the closest double value which is less than or equal to the specified expression or value and equal to a mathematical integer.

If the argument value is already equal to a mathematical integer then the result is the same as the argument. The java lang math floor is used to find the largest integer value which is less than or equal to the argument and is equal to the mathematical integer of a double value. Returns the largest integer that is less than or equal to the argument. If rounding is important to your logic you can use a static utility method in math class.

If the argument is integer then the result is integer. If the argument is nan or an infinity or positive zero or negative zero. The basic syntax of the math floor in java programming language is as shown below. Returns the smallest integer that is greater than or equal to the argument.

In the java documentation you can find that by default the math ceil double method takes a double as a parameter. Java floor method the method floor gives the largest integer that is less than or equal to the argument. 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. Since a float is a bigger than int you can convert a float to an int by simply down casting it e g.

The following function will accept positive or negative double value as an argument. Even though both float and int are 32 bit wide data type float has the higher range than integer primitive value. Java floor function syntax. The reason for that is that all the float parameters will produce the correct results when passed to the math ceil double method.

Designers of the math class didn t decide to create another method to handle float parameters.
