D
Symbol
Explanation
This instruction reverses the sign of a single-precision floating-point number in D.
Example
Before the instruction is executed, the value in (D1, D0) is the negative value 16#AE0F9000. When X0.0 switches from
_6
OFF to ON, the instruction reverses the sign of the single-precision floating-point number in (D1, D0). In other words,
after the instruction is executed, the value in (D1, D0) is the positive value 16#2E0F9000.
