To fit logarithmic curves, values of x must be positive. To fit exponential curves,
values of y must be positive. To fit power curves, both x and y must be positive.
A
 12 error will occur if a negative number is entered for these
cases.
Data values of large magnitude but relatively small differences can incur
problems of precision, as can data values of greatly different magnitudes.
Refer to "Limitations in Precision of Data" in chapter 11.
