NAME

Assert::Refute::T::Numeric - Numeric tests for Assert::Refute suite.

SYNOPSIS

Somewhere in your unit-test:

    use Test::More;
    use Assert::Refute::T::Numeric; # must come *after* Test::More

    is_between 4 * atan2( 1, 1 ), 3.1415, 3.1416, "Pi number as expected";

    within_delta sqrt(sqrt(sqrt(10)))**8, 10, 1e-9, "floating point round-trip";

    within_relative 2**20, 1_000_000, 0.1, "10% precision for 1 mbyte";

    done_testing;

Same for production code:

    use Assert::Refute;
    use Assert::Refute::T::Numeric;

    my $rotate = My::Rotation::Matrix->new( ... );
    try_refute {
        within_delta $rotate->determinant, 1, 1e-6, "Rotation keeps distance";
    };

    my $total = calculate_price();
    try_refute {
        is_between $total, 1, 100, "Price within reasonable limits";
    };

is_between $x, $lower, $upper, [$message]

Note that $x comes first and not between boundaries.

within_delta $x, $expected, $delta, [$message]

Test that $x differs from $expected value by no more than $delta.

within_relative $x, $expected, $delta, [$message]

Test that $x differs from $expected value by no more than $expected * $delta.
