Expand description
Test the lower half-precision (16-bit) floating-point element in a for special categories specified by imm8, and store the result in mask vector k using zeromask k (elements are zeroed out when the corresponding mask bit is not set). imm can be a combination of:
0x01 // QNaN
0x02 // Positive Zero
0x04 // Negative Zero
0x08 // Positive Infinity
0x10 // Negative Infinity
0x20 // Denormal
0x40 // Negative
0x80 // SNaN
