Methods summary
`public static chippyash\Type\Number\Rational\RationalType\|chippyash\Type\Number\Rational\GMPRationalType`	# `create( mixed $numerator, mixed $denominator = null )` Rational type factory Construct and return a rational. You can send in a string conforming to 'n/d' a float two ints (numerator, denominator) Rational type factory Construct and return a rational. You can send in a string conforming to 'n/d' a float two ints (numerator, denominator) Parameters `$numerator` `$denominator` Returns `chippyash\Type\Number\Rational\RationalType\|chippyash\Type\Number\Rational\GMPRationalType` \chippyash\Type\Number\Rational\RationalType\|\chippyash\Type\Number\Rational\GMPRationalType Throws `chippyash\Type\Exceptions\InvalidTypeException` InvalidTypeException

`public static`	# `setDefaultFromFloatTolerance( integer $tolerance )` Set the default tolerance for all fromFloat() operations N.B. This sets a static so only needs to be done once Set the default tolerance for all fromFloat() operations N.B. This sets a static so only needs to be done once Parameters `$tolerance`
