This is a big can o' worms.
Programming languages vary so much in their syntax and semantics that

Now that I better understand the question, there is a way to do just that
defin

exact) and then when used in a floating point expression be properly converted
to the correct form.
But, all in all, it ain't my dog.

Typically E is used for short, D is used for long and L is now being used
for
double long.
Should be.
1.5E+0 - short.
1.5D+0 - long.
1.5L+0 - double long.
What are you trying to do? Determine an interch
interchange format?
