I am setting up a C function which accepts real numbers from MathLink.
The behavior I would like to achieve is that whenever the number is
"Infinity" then the C function receives "inf" (which is a valid double-
precision-format number); and whenever the number is "Indeterminate"
then the C function receives "nan" (which is also a valid double-
Unfortunately MathLink (Mathematica 7.0 for Mac OS X x86 (64-bit))
crashes whenever I am trying to pass either Infinity or Indeterminate
to a MathLink function expecting a double-precision number.
Would you know how to solve this without going into If statements on
the Mathematica side of MathLink?
