Suppressing Scientific Notation in Output Streams with Doubles

When using the operator

1. Include the Library

#include <iomanip></iomanip>

2. Format Floating-Point Variables

setprecision(n): Sets the display precision to n decimal places.
fixed: Enforces a consistent floating-point output format.
showpoint: Displays decimal portions even when not explicitly specified.

Example Code:

outfile <p>This code ensures that floating-point variables like x will be displayed with 4 decimal places and without scientific notation. Numbers like 6.2 and 6.20 will both be output as 6.2000. Additionally, 4 will be displayed as 4.0.</p><p>By implementing these formatting options, you can suppress scientific notation for double values in output streams.</p>
