For most of these examples, you must specify a '''precision''' for the format as well in order to meet typical project requirements for the course!

Students may add to this page if they feel so inclined.

'''Beware''' `%g` formatting, its precision field specifies the ''maximum'' number of digits to use.  It will print $\frac{1}{2}$ as just `0.5`.

= C++ =
{{{#!highlight c++
std::cout << std::scientific << 0.003 << std::endl;

= Java =
{{{#!highlight java
System.println( "%e" % 0.003 );

Other methods exist with `DecimalFormat`.

"%e" % 0.003
"{:e}".format( 0.003 )
format(0.003,'.4e')
