<dd> If signs differ and the absolute values are equal according to approxEqual()
the method returns 0.0 instead of calculating the sum.
If you wanted to sum up multiple values it would be convenient not to call
approxAdd() for each value but instead remember the first value not equal to
0.0, add all other values using normal + operator, and with the result and
the remembered value call approxAdd().

<dt>Description</dt>
<dd> IEEE 754 specifies that absolute values up to 2^64 (=1.844e19) for the
radian must be supported by trigonometric functions. Unfortunately, at
least on x86 architectures, the FPU doesn't generate an error pattern for
values >2^64 but produces erroneous results instead and sets only the
"invalid operation" (IM) flag in the status word :-( Thus the application
has to handle it itself.
