The responses to numeric questions are stored as numeric data. If a response contains a real (decimal) value that has more digits than can fit in the number of columns that have been allocated, Quantum DSC rounds the digits after the decimal symbol in an attempt to make it fit. Note that the decimal symbol takes up one of the allocated columns. For example, if four columns have been allocated, 12.3456 will be round to 12.3, 123.456 will be rounded to 123, and 12345.6 will be rounded to 12345, which still won't fit.
