/* mpz_init_set_str(string, base) -- Convert the \0-terminated string
|
||
|
STRING in base BASE to a multiple precision integer. Return a MP_INT
|
||
|
structure representing the integer. Allow white space in the
|
||
|
string. If BASE == 0 determine the base in the C standard way,
|
||
|
i.e. 0xhh...h means base 16, 0oo...o means base 8, otherwise
|
||
|
assume base 10.
