numberOrDefault

numberOrDefault(value, default) → number · Type

Safely convert a value to a number, returning the default if conversion fails or the value is null.

• value (required): value to convert

• default (required): fallback number if conversion fails

echo '{"qty": "abc", "price": "19.99"}' | utlx -e '{qty: numberOrDefault($input.qty, 0), price: numberOrDefault($input.price, 0)}'
# {"qty": 0, "price": 19.99}

{
  valid: numberOrDefault("42", 0),           // 42
  missing: numberOrDefault(null, -1),        // -1
  invalid: numberOrDefault("not-a-number", 0) // 0
}
