The float type's tp_str and tp_repr both call float_repr in Objects/floatobject.c. See the 3.5.1 PyFloat_Type definition [1].

Perhaps you were reading something in reference to Python 2, which has separate float_str and float_repr functions. See the 2.7.11 PyFloat_Type definition [2] and the header file where PyFloat_STR_PRECISION is defined to be 12 digits [3].
