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.

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)

Some textbooks refer to rounding to + infinity for rounding up or - infinity for rounding down, or to 0 for rounding down positive numbers and rounding up negative numbers.

Monetary notations (euros, dollars, etc.) use a 2-digit precision format

dCode calculates the nearest multiple (rounded up/superior or rounded down/inferior to the multiple).

Example: 123 can be rounded to the closest multiple of 5 so: 125.

The ceiling rounding is in the upper rounding.

Example: 1.2 is ceil rounded to 2

Floor rounding is the lower rounding.

Example: 1.7 is floor rounded to 1

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)
