Simply use printf function.
float val=12.02300;
printf("%.8g",val);
Will give correct output. In this case it will output as 12.023
example of other output
For value=400.00; it will output 400
For value=32.122300 it will output 32.1223 .

1Was this a C or a C++ question? We do not use ````printf```` in C++. C++ uses ````iostreams````. The following will do: #include
#include – A M Apr 26 '20 at 06:53int main() { std::vector values{ 12.230030, 4.000000, 400.402100, 132.000000, 53.120203, 100.0010, 45.320030 }; for (const double d : values) std::cout << d << "\n"; return 0; }
