Public predicates

(no local declarations; see entity ancestors if any)

Protected predicates

.. index:: evaluate_integrand/2 .. _quadrature/1::evaluate_integrand/2:

evaluate_integrand/2 ^^^^^^^^^^^^^^^^^^^^^^^^

Evaluates the integrand and checks that it returns a number.

| Compilation flags: | static

| Template: | evaluate_integrand(Argument,Value) | Mode and number of proofs: | evaluate_integrand(+number,-number) - one_or_error

| Exceptions: | The integrand returns a non-numeric value: | domain_error(function_value,Value)

---

.. index:: check_bounds/2 .. _quadrature/1::check_bounds/2:

check_bounds/2 ^^^^^^^^^^^^^^^^^^

Checks that both integration bounds are instantiated numbers.

| Compilation flags: | static

| Template: | check_bounds(Lower,Upper) | Mode and number of proofs: | check_bounds(+number,+number) - one_or_error

| Exceptions: | An integration bound is a variable: | instantiation_error | An integration bound is not a number: | type_error(number,Bound)
