Decimals are usually spelt out a digit at a time. 3.14159 would be three point one four one five nine, not three point fourteen thousand one hundred and fifty nine. 37.32 would be thirty-seven point three two. If it’s not a decimal but something like a version string then you could say v3.14 is version three point fourteen, and three point one four might be confused with 3.1.4 even though you didn’t say the second point. IP addresses are a bit mixed; I’d say ten ten, but also one nine two dot one six eight.
True, but whenever Windows is having a mini-meltdown the NMI from the three finger salute is often enough to jar it out of its fixation. Plus my computer has learnt that if I hit Ctrl-Alt-Del 30 times the next time is the big red switch.
