fmaxm.q

Floating-Point Maximum-Number NaN Quad-Precision

This instruction is defined by:

Encoding

Synopsis

The fmaxm.q instruction, defined like fmax.q, writes the larger/maximum of fs1 and fs2 to fd. The value -0.0 is considered to be less than the value +0.0. If both inputs are NaN_s, the result is the canonical _NaN. If either input is NaN, the result is the canonical NaN. Signaling NaN inputs set the invalid operation exception flag, even when the result is not NaN.
