Willy Tarreau 56d1d8dab0 MINOR: tools: implement trimming of floating point numbers ... When using "%f" to print a float, it automatically gets 6 digits after the decimal point and there's no way to automatically adjust to the required ones by dropping trailing zeroes. This function does exactly this and automatically drops the decimal point if all digits after it were zeroes. This will make numbers more friendly in stats and makes outputs shorter (e.g. JSON where everything is just a "number"). The function is designed to be easy to use with snprint() and chunks: snprintf: flt_trim(buf, 0, snprintf(buf, sizeof(buf), "%f", x)); chunk_printf: out->data = flt_trim(out->area, 0, chunk_printf(out, "%f", x)); chunk_appendf: size_t prev_data = out->data; out->data = flt_trim(out->area, prev_data, chunk_appendf(out, "%f", x));		2021-05-08 10:42:11 +02:00
