fle.q

Floating-Point Less Than or Equal Quad-Precision

This instruction is defined by:

Encoding

Synopsis

The fle.q performs the specified comparison between floating-point registers fs1 and fs2, and writes 1 to integer register xd if the condition holds, and 0 otherwise.

fle.q performs what the IEEE 754-2008 standard refers to as signaling comparisons: that is, they set the invalid operation exception flag if either input is NaN. The result is 0 if either operand is NaN.
