the string representation of a rational value.
Returns
the rational value represented by string.

Remarks
Parses the specified string as a rational value.
The ASCII characters \u003a (':') and \u002f ('/') are recognized as separators between the numerator and denumerator.
For any Rational r: Rational.parseRational(r.toString()).equals(r). However, the method also handles rational numbers expressed in the following forms:
"num/den" or "num:den" => new Rational(num, den);, where num and den are string integers potentially containing a sign, such as "-10", "+7" or "5".
{@code
Rational.parseRational("3:+6").equals(new Rational(1, 2)) == true
Rational.parseRational("-3/-6").equals(new Rational(1, 2)) == true
Rational.parseRational("4.56") => throws NumberFormatException
}
