// To permit other calculations at about 100 decimal digits with some UDT,
// it is obviously necessary to define constants to this accuracy.
// However, some compilers do not accept decimal digits strings as long as this.
// So the constant is split into two parts, with the 1st containing at least
// long double precision, and the 2nd zero if not needed or known.
// The 3rd part permits an exponent to be provided if necessary (use zero if none) -
// the other two parameters may only contain decimal digits (and sign and decimal point),
// and may NOT include an exponent like 1.234E99.
// The second digit string is only used if T is a User-Defined Type,
// when the constant is converted to a long string literal and lexical_casted to type T.
// (This is necessary because you can't use a numeric constant
// since even a long double might not have enough digits).
