5.3 Floating-Point Instruction

Table 5-4 shows floating-point instructions. In cases where more than numeric type is involved, each instruction in a group is described; otherwise, only the first member of a group is described.

In the Mnemonic column, types of operands are denoted by the following lowercase letters: i for integer, s for single, d for double, and q for quad.
