Formatted output

When printing a string in Matlab, C or C++, you usually print it in Formatted output. This is useful when you need to define a custom precision for floats. Say you want to print \pi. The ouput will be 3.14159 26535 89793. However you only need a couple of decimals, so you define the precision in the formatted output parameters, and the newly formatted output will be 3.14.




Here's how to print it in C or Matlab:

pi = 3.14159 26535 89793;
output: 003.14
