If a converted result cannot be represented in the destination format, the floating-point invalid exception is raised, and if this exception is masked, the integer value 2w – 1 is returned, where w represents the number of bits in the destination format.The source operand is a YMM/XMM/XMM (low 64- bits) register or a 256/128/64-bit memory location. The destina-tion operation is a ZMM/YMM/XMM register conditionally updated with writemask k1.
