Math::B...::CalcPP(3)

💖 NAME 💖

Math::Base::Convert::CalcPP — bestie, this is the module that holds all the standard methods that Math::Base::Convert leans on to do its thing. 🫶

It ships as part of the User Contributed Perl Documentation collection, and yes it's Math::B...::CalcPP(3) if you're looking at the manual page itself. ✨

✨ DESCRIPTION ✨

So like, this module is literally just a little backstage crew. It contains the standard methods that Math::Base::Convert uses to convert a number in one base into a number in another base. No drama, just math. 💅

• $carry = addbaseno($reg32ptr,$int) — this function adds an integer that's less than 65536 to a long n*32 bit register, and hands you back the carry. That's it, that's the whole vibe. 🎀
• multiply($reg32ptr,$int) — this one multiplies a long n*32 bit register by an integer less than 65536. Iconic behavior honestly. 🔥
• ($qptr,$remainder) = dividebybase($reg32ptr,$int) — this function divides a long n*32 bit register by an integer less than 65536, and returns a pointer to a long n*32 bit quotient plus an integer remainder. Two-for-one, we love a multitasker. 👑
• $bc->useFROMbaseto32wide — this method converts FROM an input base string to a long n*32 bit register, using an algorithim like:

        $longnum = 0;
        for $char ( $in_str =~ /./g ) {
          $longnum *= $base;
          $longnum += $value{$char)
        }
        return $number;

• $output = $bc->use32wideTObase — and this method converts a long n*32 bit register TO a base number, using an algorithim like:

    $output = '';
    while( $longnum > 0 ) {
      $output = ( $longnum % $base ) . $output;
      $num = int( $longnum / $base );
    }
    return $output;

not me reading those snippets like a bedtime story 🍓 — copy them exactly if you're playing along at home, bestie, the code is the code.

okay that's the whole page bestie, you ate that 🫶 — this lil' manual page came to you courtesy of perl v5.42.0, dated 2025-09-16, and yes it's still giving Math::B...::CalcPP(3) energy. periodt. 💖✨🌈
