TRUNC formula 1
  • Parameters Required: The parameters used by the TRUNC function are identified as number and num_digits
  • Number: It is the mandatory parameter that a user wants to truncate the digits of the fractional part
  • num_digits: It is the optional parameter used to specify the number of digits to be truncated after decimal numbers. The default value of this parameter is 0 if no value is given
  • Returns: This function results in a numeric number omitting the fractional part

This function works in all kinds of excel versions, including 2007, 2010, 2013, 2016, and office 365.

If the value is given to the parameter of Num_digits

  • Value is equal to zero. The function returns the rounded value
  • The value is more than zero. It indicates the number of digits to be truncated and presented on the right side of the decimal
  • The value is less than zero. It indicates the number of digits to be truncated and presented on the left side of the decimal

Application

The Trunc function has a lot of applications in Excel

  • This excel function is useful in financial analysis to trim the values to preferred precision levels.
  • It is used in mining the time and date values from date
  • Truncating a decimal number to the nearest integer number
  • It is used when there is no need for grounding of a number

Things to Remember

  • INT and TRUNCATE excel functions are identical since they result in integer values. But, these are different when they are used with negative, For example, INT(-5.3) returns -6 since it is a lesser value, but TRUNC (-5.3) returns -5, only removing the fractional value
  • When the value of Num_digits is negative, it returns the truncated value as zero
