The above examples show how when the number and the significance arguments have the same arithmetic sign the floor function rounds the supplied number towards zero.
The floor math function differs from the floor function in these ways.
The int function short for integer is like the floor function but some calculators and computer programs show different results when given negative numbers.
In the third example of floor function in excel the number argument is a negative value 4 5 in cell b22 the significance value is also negative value 2 in cell c22.
Instead of using the floor function to round down to a multiple you can use the rounddown function to round a number down to a certain number of digits.
