point value.
Using FLOAT
While most constants are 32-bit integer values, the Propeller compiler supports 32-bit
floating-point values and constant expressions for compile-time use. Note that this is for
constant expressions only, not run-time variable expressions.
For typical floating-point constant declarations, the expression must be shown as a floating-
point value in one of three ways: 1) as an integer value followed by a decimal point and at
least one digit, 2) as an integer with an E followed by an exponent value, or 3) both 1 and 2.
For example:
The above code creates three floating-point constants.
to 0.4 and
Notice that in the above example, every component of every expression is shown as a
floating-point value. Now take a look at the following example:
