Number Matchers

Number-oriented matchers work on integer and float values unless noted otherwise.

Comparisons

expect(score).toBeGreaterThan(10);
expect(score).toBeGreaterOrEqualTo(10);
expect(score).toBeLessThan(20);
expect(score).toBeLessThanOrEqualTo(20);

Available methods:

• toBeGreaterThan(value)
• toBeGreaterOrEqualTo(value)
• toBeLessThan(value)
• toBeLessThanOrEqualTo(value)

Approximate Equality

toBeCloseTo(expected, precision = 2) compares by decimal precision.

expect(3.14159).toBeCloseTo(3.14, 2);

Numeric Type Checks

expect(total).toBeNumber();
expect(count).toBeInteger();
expect(ratio).toBeFloat();
expect(ratio).toBeFinite();

Available methods:

• toBeNumber()
• toBeInteger()
• toBeFloat()
• toBeFinite()

toBeFinite() is intended for numeric values and fails for non-finite values.
