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.


n = .005;

Floating point constants can also be expressed in a variety of  scientific notation. ‘E’ and ‘e’ are both accepted as valid exponent indicators.
