Operation:
S ROUND(SP) D
(parallel data bus move)
Description:
Take the contents of the specified source operand S, round to single precision and store the result in the
destination operand D. If S and D are the same register, this is equivalent to "Round to Single Precision"
instruction.
Input Operand(s) Precision: SEP Floating-Point.
Output Operand Precision: SP Floating-Point.
