feat: Add support for double class variables.

[divyanshub024]

Description

We need to add support for following variables from double class.

static const double nan = 0.0 / 0.0;
  static const double infinity = 1.0 / 0.0;
  static const double negativeInfinity = -infinity;
  static const double minPositive = 5e-324;
  static const double maxFinite = 1.7976931348623157e+308;

usage:

{
                    "type": "container",
                    "width": "maxFinite",
                    "height": 500,
