It would be handy to have a fully implemented log10(x) function available when you start maxima, just as mathematica and maple have. Having to define it as log10(x) := log(x) / log(10); or using log10.mac is an unnecessary hassle

    I second this request.

    Are there capabilities you want to see for log10 that are not contained in log10.mac? Is it enough, from your point of view, to add the log10.mac to the built-in functions? Thanks for your input, I appreciate it.

      Hi, I'm not the original poster, but anyway: thanks for referencing log10.mac (and for coding it!)
      In the manual there's only one reference to a decimal logarithm function:
      "Maxima does not have a built-in function for the base 10 logarithm or other bases.
      log10(x) := log(x) / log(10) is a useful definition."
      (In the entry for log(x))
      I'd say it'd be great to have that little file referenced in the manual in the same section as the other log functions.

        It would be even better if Maxima had log10(x) on board as soon as you
        start it, this function is for a large category of users (engineers)
        more important than a lot of other "exotic" functions which maxima does
        have on board.
        The lack of basic functions like sinc(x), log10(x) when you start maxima,
        is really a bummer for users who want to come over from Maple,
        Mathematica... and want to switch to the free software alternative.

        kind regards,
        Hugo
