Tool to compute roundings (integers, decimals, to multiple). Rounding a number is calculating an approximate value using its digits (rounding down floor, rounding up ceil, rounding to multiple) in the limits of the precision asked to the calculator.

Answers to Questions
How to calculate a Rounding?
dCode allows rounding to the desired number, the rounded default is closest (approximation), ie the upper value if the decisive digit is greater than or equal to 5 and the lower value if the decisive digit is less than 5.
Round to ones (no decimal dot), round to tenth (1 decimal place), round to hundredth (2 decimal places) or round to thousands (3 decimal places).
Example: 3.15 is rounded to 3.2 with 1 digit after decimal point (to tenth)
Monetary notations (euros, dollars, etc.) use a 2-digit precision format
How to calculate a Rounding to a multiple?
dCode calculates the nearest multiple (rounded up or rounded down to the multiple).
Example: 123 can be rounded to the closest multiple of 5 so: 125.
How to calculate a Ceiling Round?
The ceiling rounding is in the upper rounding.
Example: 1.2 is ceil rounded to 2
How to calculate a Floor Round?
Floor rounding is the lower rounding.
Example: 1.7 is floor rounded to 1
What is a significant figure?
The significant digits are the figures (of a decimal number) known with certainty. They depend on the measuring tool, but also on the rounding done.
Example: 0.0123 has 3 significant digits (1,2,3)
