WebApr 10, 2024 · Conclusion. The C++ setprecision function is used to format floating-point values. This is an inbuilt function and can be used by importing the iomanip library in a program. By using the setprecision function, we can get the desired precise value of a floating-point or a double value by providing the exact number of decimal places. WebMar 19, 2024 · Threading structure. I rather dislike the overall structure of the code. Rather than having two threads contending over a single location where the current estimate of \$\pi\$ is stored, I'd rather have the calculator thread compute successive approximations, and write them to a queue. The display thread would then wait on value to show up in …
