But I also use OpenCalc on the PC. And Electrodroid on my phone. And Omni Calculator: https://www.omnicalculator.com/ --- End quote --- I use the FX-991MS. You can use engineering notation directly which can be handy. |

Gosh, how many versions do they have? There's apparently an RS as well. Couldn't find anything that spelled out the differences, though. |

Engineering notation means things like 270ᴇ3 (meaning 270×103) for 270000, whereas with metric SI prefixes that’s 270k. Practically any scientific calculator can do scientific notation (exponent notation like 2.7ᴇ5) and engineering notation (same as scientific, but with the exponent always in multiples of 3, like 270ᴇ3). It’s metric SI prefixes that are rare as hen’s teeth. Edited per my reply to rsjsouza. |

Interesting; I haven't seen it called "metric" before. I learned to call them SI prefixes or SI multipliers, since in my home country we were already immersed in the metric system and the word "metric" would be redundant anyways. Perhaps my google-fu skills are lacking, but the several references on the internet that mention "metric prefixes" seem to be originated in the U.S. |

I’ll chalk that up to the neck spasm I’ve been dealing with for the past 3 days… :/ |
