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;
