void set_NaN ( sys_float &  x  )  [friend]

define routines for setting single and double precision signaling NaN The bit pattern for an SNaN is implementation defined, but this should work on most modern CPU's. The system definition is preferred, so in C++ this should be replaced by numeric_limits<TYPE>::signaling_NaN()

set_NaN - set variable or array to SNaN
