Question

Round of upto two decimal places 0.4537 ÷ 349 × 123.456​

Answer 1

Answer:

dCode allows rounding (or approximate value) from an exact value, 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 one decimal place), round to hundredth (2 two decimal places) or round to thousands (3 three 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.
