  Also mathematicians: here’s this cool new thing, I called it “infinitesimal”

  In computer engineering we have positive and negative zero.

    Also in Math.

      Unknowingly from the GP, that’s where CE got it from.

      What algebra uses negative 0?

    And, as a mathematician who has been coding a library to create scaled geometric graphics for his paper, I hate -0.0.

    Seriously, I run every number where sign determines action through a function I call “fix_zero” just because tiny tiny rounding errors pile up in floats, even is numpy.

    What do you mean? In two’s complement, there is only one zero.

      IEEE 754 floating point numbers have a signed bit at the front, causing +0 and -0 to exist.

      Specifically I was referring to standard float representation which permits signed zeros. However, other comments provide some interesting examples also.

  Limit x->0 { x } = 0 ? Noway

    Wait do you actually say “limit” instead of “limes” in English?

    source

    • something_random_tho@lemmy.world ⁨5⁩ ⁨months⁩ ago

      Yes, as in “Why can’t I hold all these limits?”

    • mexicancartel@lemmy.dbzer0.com ⁨5⁩ ⁨months⁩ ago

      I usually uses lim

  i mean, mathematically speaking, every number that isn’t zero, is further away from zero, than the number before it.

  So there is a point to the statement of “approaching zero” as well “near zero” and “about zero” since 100 probably isn’t about zero.

  Also CS nerds would like to fight you about floating point values.

    Whoa slow down there buddy. Proposing numbers before numbers like they are a given.

    • KillingTimeItself@lemmy.dbzer0.com ⁨5⁩ ⁨months⁩ ago

      as far as we can tell, mathematically, they are a given, and they never stop.

      I’ll wait for you to find the end of pi.

  “small but non-zero” is one of my favorite phrases 😅

    I like Paul Erdős’s usage if “epsilon” to refer to children

  What about large values of zero?
