The experiment I did was to show 2 different results from the same calculator to the same expression. I don't care if I have even 3 or 4 correct digits in such corner cases. For practical purposes that is a singularity point

ok,
then:
Free42: -7497258.18533
HP-15C and HP-41CX -7507225.705 (not -7.518796992e6 as we read in that site), both the same number
HP 50g: -7497089.06508 (like the Prime in Home)
old CASIO PB-110 (1983): -7497938.067
TI Voyage 200: -7497257.878
old TI 74: -7497263.499
...

For Italian speakers: "numeri del Lotto", random (approximation) numbers, hi.
