title: Value mismatch using copy data activity in ADF
body: <p>I am using copy data activity to load an xlsx file to a sql server table(columns with nvarchar datatype).</p>
  <p>I find that for some random values there is a difference in the value for 14th decimal place(I have the value upto 14 decimal places and the last digit varies)
  For example: xlsx source has 1.12345678901234 and sink has 1.12345678901235</p>
  <p>This is not happening for all values but some, however consistently happening for the same value in any number of reloads.</p>
  <p>I tried to convert to csv file using copy data activity, but still with the same output(1.12345678901235).</p>
  <p>Could anyone advise on why its the case and if there are any ways to overcome it.</p>
  <p>Thanks in advance.</p>
