Math::Base::Convert::CalcPP(3p)

NAME
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;
