vitaut 🤍❤️🤍 🇺🇦What would be a better name for the dtoa function that converts a floating-point number to a string in decimal and also works with float?
Current signature:
void dtoa(double value, char* buf);
Current signature:
void dtoa(double value, char* buf);
The current tentative name is to_string since it will give the same output as std::to_string after my fix.
John McFarlane@vitaut `fptoa`?`fpclassify` is an example of 'fp' used to mean 'any old floating-point'. The 'a' and the 'to' are appealing because similar fns, e.g. `atof` also have narrow contracts & sharp edges. (How's the long double overload coming along?)
Marcus Müller@vitaut honestly, `numtoa` if you can throw in a few int converters as well

Nikita Lisitsa@vitaut I wonder what exactly does krakatoa convert to string
Wtf a kraka is
Wtf a kraka is
@lisyarus not sure either by the conversion process is impressive

@vitaut
fod_ctsid() (float or double, convert to string in decimal), obviously@oleksandr rolls of the tongue
@vitaut @oleksandr Ah so we aim for something short and succinct as BLAS or NETLIB would have liked it (if Fortran, unlike C, didn't actually come with an actual type system that allows for automatic conversion between numeric and string type) (I mean, C does have a type system: it has function pointers, and any object but function pointers.)
(EDIT: luckily remembered that the German word "prägnant" translates to "succinct". Not something phonetically much closer.)
René Ferdinand Rivera Morell@vitaut You forgot the buf_len argument.
@grafikrobot the exact API can be tweaked, the question is about the naming
@vitaut Well.. It depends. As in the name depends on the API. As it stands I'd name it "unsafe_num2chars_dont_use_you_idiot` ;-)
@grafikrobot I do plan to add _unchecked suffix once the dust settles =)
@grafikrobot @vitaut buffer size is constant for this API, though a span could maybe be returned, no?
@JSAMcFarlane @grafikrobot it could take something span like
VZ@vitaut If you want to stay cryptic, then fptoa() would seem to be a natural choice. If your budget allows for more than a few letters and maybe even some underscores, you could go with fpnumber_to_string().
@VZ @vitaut except that sounds a lot more like functions that a) return std::string, and b) are easy to use safely. Sometimes cryptic signals caution, and this fn isn't for the casual, modern-C++ user. (I think a wrapper, `std::string to_string(double value)`, would be nice, and not too slow in many cases.)
