About Floating Point
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.
Floating-point constant expressions can be defined and used for many compile-time purposes,
but for run-time floating-point operations, the FloatMath and FloatString objects provide
math functions compatible with single-precision numbers.
