[Android.Runtime.Register("parseRational", "(Ljava/lang/String;)Landroid/util/Rational;", "")]
public static Android.Util.Rational? ParseRational (string? string);

[<Android.Runtime.Register("parseRational", "(Ljava/lang/String;)Landroid/util/Rational;", "")>]
static member ParseRational : string -> Android.Util.Rational

Parameters

string: String

the string representation of a rational value.

Returns

Rational

the rational value represented by string.

Attributes: RegisterAttribute

Exceptions

NumberFormatException

if string cannot be parsed as a rational value.

NullPointerException

if string was null

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
            }
