float @__nv_fsub_rn(float %x, float %y)

Subtract two floating point values in round-to-nearest-even mode.

Compute the difference of x and y in round-to-nearest-even rounding mode.

Note

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

Note

This operation will never be merged into a single multiply-add instruction.
