How to use the DOLLARDE function in Excel

In this article, we will learn How to use the DOLLARDE function in Excel.

Scenario :

What is fractional notation of a dollar price in decimals?  Sometimes working with financial numbers, the existing dollar price in decimals needs to be converted to the special notation with the given fraction required. 

New fractional notation = Integer price + decimal price (as integer) / fraction 

Learn more about how to convert the dollar price to required dollar notation using the DOLLARDE function below.

How to use the DOLLARDE function

DOLLARDE function converts the dollar price (in decimal) to the type of fraction notation as per given fraction argument.

Generic formula:

=DOLLARDE (fractional_dollar, fraction)

fractional_dollar : dollar value in decimal

fraction : fractional value given as integer (denominator to the decimal part)

 

Example :

All of these might be confusing to understand. Let's understand this function using an example. Here we have a list of decimal values as fractional numbers and fractional part as Integer arguments.

Use the formula :

=DOLLARDE(B4,C4)

As you can see in the above image, the DOLLARDE function returns $100.08 which is also the mathematical expression of =100(int) + 06(decimal)/8(fraction). The mathematical expression in the right column can be used to understand the function in much better way. You can copy the formula to other cells using the Ctrl + D shortcut keys or dragging down from the right bottom of the D4 cell.

As you can see all the results obtained as per mathematical operation performed using the DOLLARDE function. As you inspect the D14 cell, there's a DIV! Error. It is generated as 37/0 returns non existing value i.e. in excel it is denoted by #DIV! Error.

Now let's see how different fractional values affect the same dollar price. For example we are considering $ 3.0625 as price.

As you can see in the example shown in the above image, how different fraction arguments affect the price value. Here the arguments to the function are given directly within the function. 

You must be thinking why it is not possible to do the same task without using the function. It can be performed using the mathematical operation but there is a problem when you convert the decimal part of price to integer part.

Use the formula:

=INT(price)+(price-INT(price))*(10^n)/fraction

Here 10^n means if price value as upto 3 decimal place then n will be 3.


In the above example, we know that each price value has 2 digit decimal price so we used n = 2.

Here are some observational notes using the DOLLARDE function shown below.

Notes:

  1. The formula only works with numbers.
  2. Negative dollar price argument returns the dollar price with negative sign. But negative argument as fraction argument returns #NUM! error.
  3. Blank cells are considered as zero value. Dollar price as 0 returns zero as result but zero as fraction argument returns #DIV! error.
  4. The function returns #VALUE! Error if any argument to the function is non numeric.
