the class ParseUtil method asLong.

public static long asLong(long[] args, int index, Metadata md) {
    final int typeIndex = index << 1;
    if (typeIndex >= args.length) {
        return DEFAULT_NUMBER;
    }
    final Type type = md.getTypeById(args[typeIndex]);
    if (type == MetaType.METADATA || VoidType.INSTANCE.equals(type)) {
        return DEFAULT_NUMBER;
    }
    final int valueIndex = typeIndex + 1;
    final SymbolImpl value = md.getScope().getSymbols().getOrNull((int) args[valueIndex]);
    if (value instanceof IntegerConstant) {
        return ((IntegerConstant) value).getValue();
    } else if (value instanceof BigIntegerConstant) {
        return ((BigIntegerConstant) value).getValue().longValue();
    } else if (value instanceof NullConstant || value instanceof UndefinedConstant) {
        return 0L;
    } else {

        result = nodeFactory.createAllocaArray(runtime, type, num, alignment);
    }
    // we never want to step on allocations, only to actual assignments in the source
    createFrameWrite(result, allocate, null);
}
