Ruby Round Up To Nearest 10

You can t use the round mode for rounding up because that only rounds up fractions and not whole numbers.

Ruby round up to nearest 10.

The round is an inbuilt method in ruby returns a number rounded to a number nearest to the given number with a precision of the given number of digits after the decimal point. Usually defaults to 1 rounding to the nearest number. If you want to round down do 5. Usually defaults to 2 on most systems which would represent a base 10 decimal.

But the problem of the answer of tallgreentree is that it doesn t round up it rounds to the nearest 10. To solve this add 5 to your number in order to round up. I have tried integer round 0 1 but it gives the nearest decimal number. This can be done at either the coding end or at the database end itself.

3 should return 0 55 should return 60. Represents the rounding mode for floating point addition at the start time. 0 rounding towards zero. 123 45 round 1 123 5 round to the nearest hundred.

123 45 round 2 100. 123 45 floor 123 123 45 ceil 124 123 45 round 123 round to the nearest tenth. Other modes include 1 indeterminable. In case the number of digits is not given the default value is taken to be zero.

Here is a small function that you can add in your database to achieve this result. In an application you need to round up numbers to nearest 5 or nearest 10 all the time. Ruby s built in rounding methods are great for the basic cases like rounding to a whole number or rounding to a certain decimal place. Is there a met.

The function needs a number and ndigits which specifies the number of digits to be rounded off. When the precision is negative the returned value is an integer with at least ndigits. 1 rounding to the nearest number. Round p1 v1 p2 public returns float rounded to the nearest value with a precision of ndigits decimal digits default.
