Numeric (Real) Expressions
In expressions, integers are treated as reals; they are fully interchangeable. Numeric expressions can contain:
•
Numbers, for example: 32, 10.1.
•
Numbers can be given as as integer exponents, for example: 10 exp 5, and 5 E 6.
•
Numbers be qualified by unit names.
•
Attributes of type number, for example: XLEN.
•
Position, direction and orientation attributes which have a subscript to indicate which part of the array is required. For example, POS[2] means the second element of the POSITION attribute; that is, the northing. Note that position, direction and orientation attributes without subscripts can only be used in number array expressions.
•
The keyword PI (3.142).
•
Numeric operators.
•
Numeric functions.
