-
float @__nv_erfcxf(float %x)
Calculate the scaled complementary error function of the input argument.
Calculate the scaled complementary error function of the input argument
x, \(e^{x^2}\cdot \textrm{erfc}(x)\).Note
For accuracy information, see the CUDA C++ Programming Guide, Mathematical Functions Appendix, Single-Precision Floating-Point Functions section.
- Returns
__nv_erfcxf( \(-\infty\) ) returns \(+\infty\)
__nv_erfcxf( \(+\infty\) ) returns +0
__nv_erfcxf(
x) returns \(+\infty\) if the correctly calculated value is outside the double floating point range.
