[Bug libfortran/48925] New: Code cleanup in write_float.def
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48925 Summary: Code cleanup in write_float.def Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: libfortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: thenl...@users.sourceforge.net For improvement in code quality and possible future modifications, I suggest to separate the steps "digit generation" and "number formatting" into separate functions. 1. There should be a function "Digit generation". Input: - a floting-point number (e.g. -.123456789E+12) - the rounding mode (up/down etc.) - mode: fixed-point (F editing), or floating-point (E/ES/G), or engineering (EN) - number of significant digits (floating-point), number of decimal digits (F) Output: - a string with the digits of the rounded significand (e.g. "123457") - an integer exponent (e.g. 12), or position of the decimal separator - the sign flag (- or +) 2. There should be a function "number formatting" Input: - s.a. Output - the edit descriptor (F/E/G...) - Field width w and number of requested digits d Output: - A buffer with the formatted number (e.g. " +1.23457E+011") Function 2 is independent of the floating-point precision, so we don't need it four times for all the different real kinds, only one time.
