ROUND function

PRO BASIC

The ROUND function in Jspreadsheet Formulas Pro is a mathematical tool used to modify the precision of a number. It allows you to specify how many digits after the decimal point you want to keep. For example, if you have the number 3.14159 and you want to keep only two digits after the decimal point, you would use the ROUND function and the result would be 3.14. It's a convenient and simple way to manage numerical accuracy in your Jspreadsheet projects.

Documentation

Rounds a number to a specified number of digits.

Category

Math and trigonometry

Syntax

ROUND(number, num_digits)

Parameter Description
number The number you want to round.
num_digits The number of digits to which you want to round the number.

Behavior

The ROUND function is used to round numbers to a certain number of decimal places. Here is how it behaves with different types of input:

  • Numbers: The ROUND function works as expected with numbers, rounding them to the nearest value based on the number of decimal places specified.
  • Empty cells: If the ROUND function is applied to an empty cell, it will typically return an error because it expects a numeric input.
  • Text: If the ROUND function is applied to a cell containing text, it will return an error as it can only round numeric values.
  • Booleans: When rounding a boolean value, it will treat TRUE as 1 and FALSE as 0.
  • Errors: If the cell that the ROUND function is referencing contains an error, the ROUND function will also return an error.

Common Errors

Error Description
#VALUE! This error is returned when the ROUND function is applied to a cell containing non-numeric data, like text.
#NUM! This error is returned when the number of decimal places specified for rounding is less than zero.
#REF! This error is returned when the cell reference is not valid. This might happen if the referenced cell was deleted.

Best practices

  • Always ensure that the input to the ROUND function is numeric. Non-numeric inputs will result in errors.
  • Be mindful of the fact that ROUND function does not just truncate the number, but rounds it. i.e., ROUND(1.5, 0) will return 2, not 1.
  • Be aware that the ROUND function will treat boolean values as 1 for TRUE and 0 for FALSE.
  • Double-check your cell references to avoid #REF! errors. If you delete a cell that is referenced by a ROUND function, it will return an error.

Usage

A few examples using the ROUND function.

ROUND(3.14159, 2) returns 3.14  
ROUND(99.95, 0) returns 100  
ROUND(1234.56789, -2) returns 1200
