Converts a dollar price expressed as an integer part and a fraction part, such as 1.02, into a dollar price expressed as a decimal number. Fractional dollar numbers are sometimes used for security prices.
The fraction part of the value is divided by an integer that you specify. For example, if you want your price to be expressed to a precision of 1/16 of a dollar, you divide the fraction part by 16. In this case, 1.02 represents $1.125 ($1 + 2/16 = $1.125).
Syntax
DOLLARDE(fractional_dollar,fraction)

Fraction is the integer to use in the denominator of the fraction.
Remarks
 If fraction is not an integer, it is truncated.
 If fraction is less than 0, DOLLARDE returns the #NUM! error value.

Formula 
Description (Result) 
=DOLLARDE(1.02,16) 
Converts 1.02, read as 1 and 2/16, to a decimal number (1.125). Because the fraction value is 16, the price has a precision of 1/16 of a dollar. 
=DOLLARDE(1.1,32) 
Converts 1.1, read as 1 and 10/32, to a decimal number (1.3125). Because the fraction value is 32, the price has a precision of 1/32 of a dollar.
