These functions are useful to tell if some type is a floating point type.

This is useful in a templated function, where the processing can vary depending on whether the type is FP or not (e.g. blank handling).

static void casacore::FitsFPUtil::setNaN

(

float &

val

)

static void casacore::FitsFPUtil::setNaN

(

double &

val

)

[static]

For blanking purposes, we need to be able to get a NaN.

The NaN we set is all bits on.
