Content
A couple of preparatory commits: r82025: In _Py_dg_strtod, 'e' now represents the adjusted exponent rather than the base exponent; that is, the input value is of the form +- m * 10**e with 0.1 <= m < 1.0. It's easier to produce such an 'e' from the parsing stage if we care about detecting overflow and underflow. r82031: Update the s2b function: remove a premature optimization in order to make s2b more general and its correctness more easily verifiable; alter the way that the input string is parsed so that it doesn't depend on nd0 being in the range [0, nd].
