The following are examples of valid constants:
Here is an example declaring an integer constant and two floating-point constants.
CON
The above code sets
the last expression required
treats it as a floating-point value.
The Propeller compiler handles floating-point constants as a single-precision real number as
described by the IEEE-754 standard. Single-precision real numbers are stored in 32 bits, with
a 1-bit sign, an 8-bit exponent, and a 23-bit mantissa (the fractional part). This provides
approximately 7.2 significant decimal digits.
For run-time floating-point operations, the FloatMath and FloatString objects provide math
functions compatible with single-precision numbers.
See
FloatString objects for more information.
