Title: Complex free quantity ?
Post by microsys on Oct 8^th, 2007, 5:41am

Hello designer's community!
I have a question about using free quantities types.
The sytax rule for a free quantity declaration specify that the type must be either a floating-point type or a composite type whose scalar elements are all floating point types.
Complex type is defined in IEEE.MATH_COMPLEX package as:

type COMPLEX is record RE, IM: real; end record;

Can I deduce that using of free quantities of complex type is allowed?
Thanks in advance for your answers.

You are correct. As you have already pointed out, quantities can be of a composite type whose scalar sub-elements are floating point types.

You are also able to define composite branch quantities.
