If the PV exceeds 9999999 or -999999, the PV is divided by 1000 and “K” is
appended to the result, allowing a maximum value with multiplier of 999999K or
-99999K.
If the PV exceeds 999999K or -99999K, the PV is divided by 1,000,000 and
“M” is appended to the result, allowing a maximum value with multiplier of
999999M or -99999M.
