I will argue that the answer should be yes.
epicsTypes is the proposed set of primitive types are well as proposed
definition for string, array, and enum.
Without agreeing on a set of primitive data types, including the
precision of each type, mismatches between data sources and consumers
can easily occur.
Corba IDL, Java, and C# all use types short, int, long, float, and
double but ALL define the exact precision for each. In fact they all use
the sdame precision, i.e.
short 16 bits
int 32 bits
long 64 bits
float 32 bit IEEE float
double 64 bit IEEE float.
