The exclusiveMinimum keyword restricts number instances to be strictly greater than the given number.

Remember that JSON Schema is a constraint-driven language. Therefore, non-number instances successfully validate against this keyword. If needed, make use of the type keyword to constraint the accepted type accordingly.

Examples
