Overview

Validates values against XSD fractionDigits facet

The fractionDigits facet specifies the maximum number of digits in the fractional part (after decimal point) for decimal types.

Examples:

Validating fraction digits

facet = Lutaml::Xsd::FractionDigits.new(value: "2")
validator = FractionDigitsFacetValidator.new(facet)
validator.valid?("123.45")   # => true (2 fraction digits)
validator.valid?("123.4")    # => true (1 fraction digit)
validator.valid?("123.456")  # => false (3 fraction digits)
validator.error_message("123.456")
# => "Value has 3 fraction digits, exceeds maximum of 2"

def error_message(value)
  actual_fraction = count_fraction_digits(value)
  "Value has #{actual_fraction} fraction digits, exceeds " \
    "maximum of #{facet_value}"
end

#valid?(value) ⇒ Boolean

Validate value has correct fraction digits

Parameters:

  • value (String, Numeric) —

    The value to validate

Returns:

  • (Boolean) —

    true if fraction digits <= maximum, false otherwise
