The FPU supports decimal numbers in BCD (binary-coded decimal). Presumably these large powers of 10 are useful for BCD conversion, especially since they are near other BCD-related masks. But they aren't normal floating-point numbers, so they don't have exponent parts. Yes, constants 6 and 7 look like they should be part of the same sequence, but nothing that I try will work.
