| I need to verify whether or not position and orientation data is valid;
| valid in the sense of being a valid number. Sometimes I receive data
| (via ethernet packets) that is NaN, "not a numer" and I need to make sure
| that it IS a valid floating point number before using it. Are there any
| routines already available that check for valid floating point
| representation?

isnanf() or fpclass() (man isnan for more details).
