+ NUM
+ Y. Orlarey, (c) Grame 2002
+------------------------------------------------------------------------------
+Nums are tagged unions of ints and floats. Nums are completly described by
+the num.h file, there is no num.cpp file.
+
+ API:
+ ----
+ num(10); : num with int content
+ num(3.14159); : num with double content
+
+ num op num : op is any C binary operator
+
+ type(num) : 0 = int, 1 = double
+ int(num); : int content of num or conversion
+ double(num); : double content of num or conversion
+
+ History :
+ ---------
+ 2002-02-08 : First version
