Missing Values

Some of the functions in the PyIMSL Math Library allow the data to contain missing values. These functions recognize as a missing value the special value referred to as “not a number,” or NaN. The actual value is different on different computers, but it can be obtained by reference to the PyIMSL function machine, described in Chapter 12, “Utilities.”

The way that missing values are treated depends on the individual function and is described in the documentation for the function.
