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;
