How do I maintain the format of numbers from excel once the data is merged
into a word document. I have tried "custom" formatting as well as numbers
with 2 decimal places but the numbers still come in incorrectly in the word
document, e.g. 129.9999999990 rather than 130.00 or if it is not a
calculated number, then it might come in as 130.0 rather than 130.00.
