func Parse

func Parse(s string) Descriptor

Parse parses a rule descriptor in the following format, or panics:

• bv and rad are the names of tokens formatted as decimal numbers expressed using ASCII digits with spaces, period, and commas ignored.
• bv specifies the rule's base value. The rule's divisor is the highest power of 10 less than or equal to the base value.
• bv/rad: The rule's divisor is the highest power of rad less than or equal to the base value.
• -x: The rule is a negative-number rule.
• x.x: The rule is an improper fraction rule.
• 0.x: The rule is a proper fraction rule.
• x.0: The rule is a default rule.
• Inf: The rule for infinity.
• NaN: The rule for an IEEE 754 NaN (not a number).
