Hello Feng
The fplib only exists in Classic CodeWarrior. User can find its example projects under CodeWarrior folder:
C:\Program Files (x86)\Freescale\CodeWarrior for DSC56800E v8.3\(CodeWarrior_Examples)\Floating Point Examples
The functionality that this lib supports includes:
1. Basic floating-point operations: addition, subtraction, multiplication, division
2. Conversion to and from integer (16-bit and 32-bit) and floating-point format, both round-to-nearest-even and toward-zero versions
3. Comparison functions
4. Rounding functions: floor, ceil, round, trunc, rint
5. Function for controlling floating-point state as defined in [2]: getround, setround, testexcept, getexceptflag, setexceptflag, clearexcept
What kind of function do you need? Indeed, 56800E compiler itself does have support for C99 support functions, including trigonometric, hyperbolic, power, absolute value functions, exponential and logarithmic functions. User does not need to use fplib.
