 +====== floating point constants   ======
 +
 +Similar to integer constants, floating point constants are used to make code more readable. Floating point constants are swapped at compile time for the value to which the expression evaluates.
 +
 +Examples:
 +
 +<code arduino>n = .005; </code>
 +
 +
 +Floating point constants can also be expressed in a variety of  scientific notation. 'E' and 'e' are both accepted as valid exponent indicators.
