ContinuousFieldFunction class final

A function that returns a ContinuousField when evaluated.

Use ContinuousFieldFunction.evaluate to compute the result of this function.

Results are updated when changes are made to parameters of this function (or to parameters of functions from which it is composed).

Operator overloads are available via ContinuousFieldOperators to combine fields and values using *, +, -, /, and unary -.

Calculations that evaluate to infinity or NaN produce an indeterminate value.

Values are represented as 32-bit floating-point numbers, so arithmetic operations will wrap at the boundaries of this type.
