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 = 0.005; // 0.005 is a floating point constant
Floating point constants can also be expressed in a variety of scientific notation. ‘E’ and ‘e’ are both accepted as valid exponent indicators.
|floating-point constant||evaluates to:||also evaluates to:|
|2.34E5||2.34 * 10^5||234000|
|67e-12||67.0 * 10^-12||.000000000067|
