Overview

Validates XSD decimal type

The decimal type represents arbitrary-precision decimal numbers. Valid values include integers and decimals with optional sign.

Examples:

Validating decimal values

validator = DecimalValidator.new
validator.valid?("123.45")    # => true
validator.valid?("-0.5")      # => true
validator.valid?("+3.14")     # => true
validator.valid?("100")       # => true
validator.valid?(".5")        # => true
validator.valid?("5.")        # => true
validator.valid?("abc")       # => false
