Int64:
static Int64 parseRadix(String s, int radix) {
static Int64 parseInt(String s) => _parseRadix(s, 10);
static Int64 parseHex(String s) => _parseRadix(s, 16);
Int32:
static Int32 parseRadix(String s, int radix) {
static Int32 parseInt(String s) => new Int32.fromInt(int.parse(s));
static Int32 parseHex(String s) => parseRadix(s, 16);
int:
external static int parse(String source,
{ int radix,
int onError(String source) });
Int32/64 have toHexString().
They are inconsistent in how they handle negative values and in the case of the alphabetic characters.
Int32/64 are missing a lot of methods defined on num.
Most are probably not that interesting (isNaN, isInfinite, roundToDouble() ...)
This should be implemented:
double toDouble(); // I have seen a workaround implemented as double.parse(thing64.toString())
This might be useful:
IntXX clamp(lowerLimit, upperLimit);
These have been added to int and would make sense on IntXX:
int bitLength();
IntXX toSigned(int width);
IntXX toUnsigned(int width);
int is missing bitCount() (issue dart-lang/sdk#5798).
