36     The __fp_powsodd() function calculates a polynom with only odd
37     powers of x.  Result is rounded.
38
39   Input:
40     rA3.rA2.rA1.rA0	- an 'x' arg
41     ZH.ZL		- table address (in flash low 64K memory)
42
43   Notes:
44     * As __fp_powsodd() is one of base function, square() is't used.
