Summary of floating-point instructions

A summary of the floating-point instructions. Not all of these instructions are available in all floating-point versions.

The following table shows a summaryof floating-point instructions that are not available in Advanced SIMD.

Note

Floating-point vector mode is not supported in ARMv8. UseAdvanced SIMD instructions for vector floating-point.
