Title: RK Record (0x027E)
Description: An internal 32 bit number with the two most significant bits storing the type. This is part of a bizarre scheme to save disk space and memory (gee look at all the other whole records that are in the file just "cause"..,far better to waste processor cycles on this then leave on of those "valuable" records out). We support this in READ-ONLY mode. HSSF converts these to NUMBER records REFERENCE: PG 376 Microsoft Excel 97 Developer's Kit (ISBN: 1-57231-498-2)

The mechanism for determining the value is dependent on the two low order bits of the raw number. If bit 1 is set, the number is an integer and can be cast directly as a double, otherwise, it's apparently the exponent and mantissa of a double (and the remaining low-order bits of the double's mantissa are 0's).
If bit 0 is set, the result of the conversion to a double is divided by 100; otherwise, the value is left alone.
