I asked dmalcolm on IRC if int or Py_ssize_t should be used:

"this is the number of digits to use in the floating point representation, right? it strikes me that if you're overflowing an int, you're asking for a very very very long string" (yes, INT_MAX is usually 2^31)

"... looking at usage of precision seems to ultimately land in Python/dtoa.c, which uses int..."
