The following functions are deprecated and will be removed from expl3 at the end of 2015: - \int_to_decimal:n - \int_to_hexadecimal:n - \int_to_octal:n - \int_from_decimal:n - \int_from_hexadecimal:n - \int_from_octal:n To replace these, the following functions are introduced: - \int_to_dec:n - \int_to_Hex:n - \int_to_oct:n - \int_from_dec:n - \int_from_hex:n - \int_from_oct:n In addition, the new function - \int_to_hex:n is introduced. Note that for the creation of hexadecimal numbers, there are now separate functions to create lower and upper case letters in the output.
