14.4.42. Negate

The Negate block outputs the negation of the input value.

The Output datatype mode determines how the block infers its output data type:

  • Inherit via internal rule. The output data type is the same as the input data type.
  • Inherit via internal rule with word growth. The output data type is the same as the input data type. If the input data type is fixed-point, word growth is applied to the output data type.
