	description: "Convert base 32 numeric strings to ${NUMERIC} types"
	notes: "[
		Base 32 strings use the character ranges `0 .. 9, A .. V, a .. v' to represent 5 bit numbers 0 to 31.

		The strings '0Y' and '0y' are interpreted as a prefix for base 32 numbers in the same way
		as '0x' '0X' indicate a hexadecimal number
