For calculator that used BCD, *2 /2 trick only work if X is "filled" with digits.
But, not always. On HP-12C, X=9.999999995, DEG->DMS = 9.5960 (exact)

OK, but at least for simple and usual calculations (in BCD), it removes the annoying "60 seconds bug". For example, DEG->DMS(DMS->DEG(0.08)) goes back to 0.08, and not 0.0760.
