Error Handling

Maths.js validates inputs for safety and predictability.

Error types

• TypeError: Thrown for invalid types, non-finite values, or non-integers where integers are required.
• RangeError: Thrown for empty collections where values are required, out-of-range parameters, or invalid bounds.

Common cases

• Maths.avg() throws RangeError because at least one value is required.
• Maths.factorial(2.5) throws TypeError because n must be an integer.
• Maths.factorial(-1) throws RangeError because n must be non-negative.
• Maths.percentile([1, 2, 3], 101) throws RangeError because p must be between 0 and 100.
• Maths.clamp(1, 10, 0) throws RangeError because min must be less than or equal to max.
