64bit integer long type

PythonJS now has a new static type long that can be used to mark a variable as a 64bit integer, see this commit. JavaScript has no native support for native 64bit integers, so the translator will use the Long.js API to construct a Long object and call the appropriate methods for math and comparison logic.

python input

def main():
 long x = 65536
 long y = x * x
 long z = 4294967296
 TestError( y==z )

 long a = z + z
 long b = 8589934592
 TestError( a==b )

 TestError( y < b )
 TestError( b > y )

 TestError( y <= b )
 TestError( b >= y )

javascript output

main = function() {
  if (__NODEJS__==true) var long = require('long');
  
  x = long.fromString("65536");
  y = x.multiply(x);
  z = long.fromString("4294967296");
  TestError( y.equals(z) );
  a = z.add(z);
  b = long.fromString("8589934592");
  TestError( a.equals(b) );
  TestError( y.lessThan(b) );
  TestError( b.greaterThan(y) );
  TestError( y.lessThanOrEqual(b) );
  TestError( b.greaterThanOrEqual(y) );
