Round if decimal number is less than

This tutorial shows how to round if a decimal number is less than a specific number using an Excel formula, with the IF, ABS, TRUNC and ROUND functions

EXCEL FORMULA 1. Round if decimal number is less than

EXCEL

Hard coded formula
Round if decimal number is less than
Cell reference formula
Round if decimal number is less than
=IF(ABS(5.3-TRUNC(5.3))<0.4,ROUND(5.3,0),5.3)
=IF(ABS(B7-TRUNC(B7))<$C$4,ROUND(B7,0),B7)
GENERIC FORMULA

=IF(ABS(value-TRUNC(value))<less_value,ROUND(value,0),value)

ARGUMENTS
value: The value that you want to round if it's less than the decimal number.
less_value: The less than decimal number.

GENERIC FORMULA

=IF(ABS(value-TRUNC(value))<less_value,ROUND(value,0),value)

ARGUMENTS
value: The value that you want to round if it's less than the decimal number.
less_value: The less than decimal number.

EXPLANATION

This formula uses the TRUNC function to return the truncated number of the number that is being tested. It then subtracts that number from the exact number that is being tested to return the decimal value of the number that is to be rounded. The ABS function is used to return the absolute number, therefore, returning the result as a positive number. The IF function is then used to check if the decimal number derived through the use of the ABS and TRUNC functions is less than the specified decimal number. If the IF function returns a TRUE value, meaning that the number that is being tested is less than a specific decimal number, the formula will round the number through the use of the ROUND function. If the number is greater than or equal to the specific decimal number the formula will return the exact number that is being tested, without rounding it.

Click on either the Hard Coded or Cell Reference button to view the formula that has the less than decimal value and the number that is being tested directly entered into the formula or referenced to specific cells.
