Fixed-Point Context-Sensitive Constants

You can conveniently use fixed-point constants without using the data properties dialog or Stateflow Explorer, by using context-sensitive constants. Context-sensitive constants are constants that infer their types from the context in which they occur. They are written like ordinary constants, but have the suffix C or c. For example, the numbers 4.3C and 123.4c are valid fixed-point context-sensitive constants you can use in action language operations.

Note    Both operands of a binary operation cannot be context-sensitive constants.

While fixed-point context-sensitive constants can be used in context with any types (for example, int32 or double), the primary motivation for using them is with fixed-point numbers. The algorithm that computes the type to assign to a fixed-point context-sensitive constant depends on the operator, the types in the context, and the value of the constant. It provides a "natural" type, providing maximum accuracy without overflow.
