SqlServer digital information with respect to the decimal point, the decimal point to remove extra zeros

demand:

       For extra zeros after the decimal point with digital information, remove the decimal point

Possible presence of:

    1, within the accuracy of, any excess of zero eg: 1234.3400 desired outcome is 1234.34

    2, the precision becomes large extra zeros occur, there is no actual data or fractional eg: 1234.0 desired result 1234

   3, the end of the data for the decimal point, but no actual decimals eg:. 1234 want results 1234
