+ | ====== 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. | ||
+ | |||
+ | <code arduino> | ||
+ | |||
+ | floating-point evaluates to: also evaluates to: | ||
