# Math::Base::Convert::CalcPP(3pm)

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;
  ```
