Math Floor Proof

The following example illustrates the math floor double method and contrasts it with the ceiling double method.

Math floor proof.

To round a number up to the nearest integer look at the math ceil method. Como floor es un método estático de math siempre debe usarse como math floor en lugar de usarlo como un método de un objeto math creado. In mathematics and computer science the floor function is the function that takes as input a real number x displaystyle x and gives as output the greatest integer less than or equal to x displaystyle x denoted floor x displaystyle operatorname floor x or x displaystyle lfloor x rfloor. If the passed argument is an integer the value will not be rounded.

The math floor function returns the largest integer less than or equal to a given number. Double values 7 03 7 64 0 12 0 12 7 1 7 6. Console writeline value ceiling floor n. Foreach double value in values console writeline 0 7 1 16 2 14 value math ceiling value math floor.

Some say int 3 65 4 the same as the floor function others say int 3 65 3 the neighbouring integer closest to zero or just throw away the 65.

The int function short for integer is like the floor function but some calculators and computer programs show different results when given negative numbers. The floor method rounds a number downwards to the nearest integer and returns the result.
