Math::Base::Convert::CalcPP - standard methods used by Math::Base::Convert

DESCRIPTION

This module contains the standard methods used by Math::Base::Convert to convert from one base number to another base number.

• $carry = addbaseno($reg32ptr,$int)

  This function adds an integer < 65536 to a long n*32 bit register and returns the carry.

• multiply($reg32ptr,$int)

  This function multiplies a long n*32 bit register by an integer < 65536

• ($qptr,$remainder) = dividebybase($reg32ptr,$int)

  this function divides a long n*32 bit register by an integer < 65536 and returns a pointer to a long n*32 bit quotient and an integer remainder.

• $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

  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;
