Right...


The list I had was for fixed-size formats, not variable ones.

i.e.
"half" - 16 bit floating point (storage only)
"float" - 32 bit floating point (a.k.a. single)
"double" - 64 bit floating point
"extend" - 80 bit floating point (or "extended")
"quad" - 128 bit floating point (future use)

Where "real" would just be an alias, and not a language type.
