standard methods used by Math::Base::Convert

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;
