Decimal Places

Hello to all and thank you for taking time to read this.

I have a simple formula that calculates 9 places to the right of the decimal point. Is there anyway to calculate only 2 places to the right of the decimal point without using the ROUND function ?

I ask this question because it takes ions to calculate several dozen worksheets with 10's of thousands of rows. If I only have 2 decimal places; i.e. 10.23 instead of 10.239870985 it would speed up the time it takes to compute the final answer.

I created a separate macro to round the answer to 2 decimal places and it takes foreverrrrrrrrrrrr. There must be an easier way.

Formula = "=(A2-B2)/ B2 * 100"

Aloha To All
