Types of artihmetic operations
Updated to Red for Windows version 0.6.2 built 7-Jun-2017/15:13:57+2:00
The table gives type of first operand, type of second operand, result type
for + (add), - (subtract), * (multiply), / (divide), // (modulo) and % (remainder)
For vectors, the element type is distinguished.
There is one case (time with time) where the result type is not the same
for all allowed operations.
After each type combination, the reverse combination is given.
The fourth column gives the operators for which the combination is forbidden.
If the result type is error, the combination is forbidden for all operators.
The order of types is: char integer float percent pair tuple vector (of char etc.)
