Function Documentation

radix_type guessbase (  const std::string &  s, radix_type  b )

Guess the base of a number in a string. Uses the first few characters to guess what base the number is. Parameters: s  String to examine b  Default base to check the number against Returns: Likely base of number in s

string::size_type isNum (  const std::string &  s, radix_type  b )

Count the number of digits in a valid number. Parameters: s  String to examine b  Default base to use Returns: Number of digits, starting from the left, that contain a valid number

void setchunk (  mpn_::radix_type  b, std::string::size_type &  chunksize, mpn_::limb_type &  chunk )

Sets the chunk size for a particular base. A chunk is the largest power of the base that can fit inside a limb. Parameters: b  Base to find the chunk of chunksize  The exponant of the base that creates the chunk chunk  The actual power of b

void stringclean (  std::string &  s, mpn_::radix_type  b, int  clear_zero )

Clean out the strings that will be converted with mpn_::setString(). Parameters: s  String to clean b  Base to clean for clear_zero  Extraneous zeros will be removed starting from: clear_zero = 0: none clear_zero < 0: left clear_zero > 0: right
