float @__nv_y0f(float %x)

Calculate the value of the Bessel function of the second kind of order 0 for the input argument.

Calculate the value of the Bessel function of the second kind of order 0 for the input argument x, \(Y_0(x)\).

Note

For accuracy information, see the CUDA C++ Programming Guide, Mathematical Functions Appendix, Single-Precision Floating-Point Functions section.

Returns

Returns the value of the Bessel function of the second kind of order 0.

  • __nv_y0f(0) returns \(-\infty\).

  • __nv_y0f(x) returns NaN for x < 0.

  • __nv_y0f( \(+\infty\) ) returns +0.

  • __nv_y0f(NaN) returns NaN.
