Assertions to Check Properties of Numbers

A set of predicates and assertions for checking the properties of numbers. This is mainly for use by other package developers who want to include run-time testing features in their own packages. End-users will usually want to use assertive directly.

A set of predicates and assertions for checking the properties of numbers. Most of the documentation is on the assertive page. End-users will usually want to use assertive directly.


To install the stable version, type:


To install the development version, you first need the devtools package.


Then you can install the assertive.numbers package using



is_even and is_odd check for even or odd numbers. is_divisible_by generalizes the concept.

is_finite, is_infinite, is_negative_infinity, and is_positive_infinity check for infiniteness.

is_nan and is_not_nan check for NaN (or not).

is_in_range checks for numbers in a range. is_in_closed_range, is_in_open_range, is_in_left_open_range, is_in_right_open_range, is_negative, is_non_negative, is_positive, is_non_positive, is_percentage, and is_proportion provide more specialized alternatives.

is_imaginary and is_real check for imaginary or real numbers.

is_whole_number check for whole numbers.

is_equal_to, is_not_equal_to, is_greater_than, is_greater_than_or_equal_to, is_less_than, and is_less_than_or_equal_to check relational operators.


Predicates all return a vector and have two corresponding assertions. For example, is_even has assert_all_are_even and assert_any_are_even.
