Last week I reported that I had a working parser for Java source code implemented as a Perl 6 grammar. Well, a dozen or so bugs later, it actually works now. Out of 7,000+
public static final double MAX_VALUE = 0x1.fffffffffffffP+1023;
public static final double MIN_NORMAL = 0x1.0p-1022;
public static final double MIN_VALUE = 0x0.0000000000001P-1022;
...
public static final float MAX_VALUE = 0x1.fffffeP+127f;
public static final float MIN_NORMAL = 0x1.0p-126f;
public static final float MIN_VALUE = 0x0.000002P-126f;
Hex notation for rational numbers -- what an interesting idea. I've never encountered that before. It appears that this notation first appeared in the 3rd edition of the Java language specification.
This seems to me like a notation worth adding to Perl 6, given its inherent precision advantages over decimal notation.
