working ucompare() for haxe.Int64 java and cs platforms (using my internal type defintions, sorry)
public static function ucompare(x:HaxeInt64abs,y:HaxeInt64abs):Int {
#if ( java || cs )
// unsigned compare library code does not work properly for these platforms
if(HaxeInt64Typedef.isZero(x)) {
if(HaxeInt64Typedef.isZero(y)) {
return 0;
} else {
return -1; // any value is larger than x
}
}
if(HaxeInt64Typedef.isZero(y)) { // if we are here, we know that x is non-zero
return 1; // any value of x is larger than y
}
if(!HaxeInt64Typedef.isNeg(x)) { // x +ve
if(!HaxeInt64Typedef.isNeg(y)){ // both +ve so normal comparison
return HaxeInt64Typedef.compare(x,y);
}else{ // y -ve and so larger than x
return -1;
}
}else { // x -ve
if(!HaxeInt64Typedef.isNeg(y)){ // -ve x larger than +ve y
return 1;
}else{ // both are -ve so the normal comparison
return HaxeInt64Typedef.compare(x,y); //eg -1::-7 gives -1--7 = +6 meaning -1 > -7 which is correct for unsigned
}
}
#else
return HaxeInt64Typedef.ucompare(x,y);
#end
