i’m trying to read a number with length greater than 12 digits from excel file using c# using below query
"select Format([F1], 'Number') as Code";
But i get only 12 digits correctly and the rest of the numbers are converted into zeroes.Why is it so??

According to MSDN:
Excel follows the IEEE 754 specification on how to store and calculate floating-point numbers. Excel therefore stores only 15 significant digits in a number, and changes digits after the fifteenth place to zeroes.
To work around this behavior, format the cell as text. The cell can then display up to 1,024 characters.
