3.81. __nv_erfcx
Prototype:
double @__nv_erfcx(double %x)
Description:
Calculate the scaled complementary error function of the input argument x, .
Returns:
-
__nv_erfcx( ) returns
-
__nv_erfcx( ) returns +0
-
__nv_erfcx(x) returns if the correctly calculated value is outside the double floating point range.
