The Fixed Point block set—listed under the Blocks menu—consists of 30+ blocks that let you design and simulate the performance of fixed-point algorithms prior to code generation and execution on an embedded platform.

When you insert a fixed-point block into a diagram, the block displays specific information about the block. For example, the const block appears as follows:

•**1:** Indicates the const value

•**fx:** Indicates fixed point

•**4.16:** Indicates the fixed-point format, with 16 total bits and 4
bits to the left of the radix point. represents the const value

•**Yellow connector:** Indicates Scaled Int. To display connectors,
activate **Connector Labels** and **Data Type** in the **View**
menu.

The Fixed Point Const dialog lets you manipulate the const value, word size, and radix point.

The dialog also shows the **Representable Range**; that
is, the range of acceptable values based on the **Radix Point** and **Word
Size** parameters. Increasing the **Radix Point** value increases the
range; decreasing the value, decreases the range.

The Learning Center provides several fixed-point videos to help get you started using the Fixed Point block set.
