v256 Vector
Round the packed single-precision (32-bit) floating-point elements in a using the rounding parameter, and store the results as packed single-precision floating-point elements in dst.
____ VROUNDPS ymm1,ymm2/v256,imm8 Round the four single-precision floating-point values values in the source operand by the rounding mode specified in the immediate operand and place the result in the destination. The rounding process rounds the input to an integral value and returns the result as a double-precision floating-point value. The Precision Floating Point Exception is signaled according to the immediate operand. If any source operand is an SNaN then it will be converted to a QNaN.
