MIN_REAL_TYPE

static final int MIN_REAL_TYPE

The smallest type tag that represents reals as opposed to integers. You can see whether a type tag represents reals or integers by comparing the tag to this constant: all tags less than this constant represent integers, and all tags greater than or equal to this constant represent reals. Of course, you must also check for NONNUMERIC, which means it is not a number at all.
