    // that when a value of ***type double*** is added to a ParameterSetDescription
    // the EXACT same value of type double will be created and passed to the
    // ParameterSet after the cfi files have been read.  The tricky part
    // is these values usually appear in the C++ code and cfi file as text
    // strings (in decimal form).  We do our best to force the text
    // string in the C++ code to be the same as the text string in the
    // cfi file by judiciously rounding to smaller precision when possible.
    // But it is not always possible to force the text strings to be the
    // same.  Generally, there are differences when the text string in the
    // C++ code has many digits (probably more than a human will ever type).
    // Even in cases where the text strings differ, the values stored in
    // memory in variables of type double will be exactly the same.
    // The alternative to the approach here is to store the values as strings,
    // but that approach was rejected because it would require the
    // ParameterSetDescription to know how to parse the strings.
