Rounding

Specify the amount of decimal places to round an answer to. This will override the line’s default precision settings.

# Rounding to a particular number of decimal places
1/3 to 2 dp                     | 0.33
π to 5 digits                   | 3.14159

# Rounding up and down
5.5 rounded                     | 6
5.5 rounded down                | 5
5.5 rounded up                  | 6

# Rounding to nearest x
37 to nearest 10                | 40
$490 rounded to nearest hundred | $500
2,100 to nearest thousand       | 2,000

# Rounding up and down to nearest x
21 rounded up to nearest 5      | 25
17 rounded down to nearest 3    | 15

Function	Name	Behaviour

This is useful for measurements in woodworking and other tasks that use fractional increments.
