--- Comment #5 from Aleksei <alexsyrezerv at mail dot ru> ---
this variant more clear.. 4 symbol after point// may by c++ has modification
for set symbols after decimal point ?
```
void func_float_point(std::ostream& os, const double& value, const
mcx::convert_info_t& cv) {
char buf[buf_size];
snprintf(buf, buf_size - 1, "%0*.*f", cv.size, cv.pos, value);
os << buf;
}
```
