Floating Point Instructions
FNEG
Instruction Fields:
5-100
Effective Address field—Determines the addressing mode for external operands.
R/M field—Specifies the source operand address mode.
Source Specifier field—Specifies the source register or data format.
If R/M = 0, this field is unused and should be all zeros.
If R/M = 1, specifies the location of the source operand. Only data addressing modes
0 — The operation is register to register.
1 — The operation is < ea > to register.
If R/M = 0, specifies the source floating-point data register.
If R/M = 1, specifies the source data format:
can be used as listed in the following table:
*This encoding will cause an unimplemented data type exception to allow
000 — Long-Word Integer (L)
001 — Single-Precision Real (S)
010 — Extended-Precision Real (X)
011 — Packed-Decimal Real (P)*
100 — Word Integer (W)
101 — Double-Precision Real (D)
110 — Byte Integer (B)
