Hi
BP 7.0 Language Guide lists 5 floating-point types:
type range significant size digits bytes -39 38 Real 2.9 x 10 .. 1.7 x 10 11-12 8
-45 38 Single 1.5 x 10 .. 3.4 x 10 7-8 4
-324 308 Double 5.0 x 10 .. 1.7 x 10 15-16 8
-4932 3932 Extended 3.4 x 10 .. 1.1 x 10 19-20 10
63 63 Comp -2 + 1 .. 2 + 1 19-20 8
(note: their book lists comp as a floating-point type. to me it looks like a signed 64 bit integer.)
*****************
glibc-2.1.3 lists support for 3 floating-point types:
DoubleWord ( 64 bits ) TripleWord ( 96 bits ) QuadWord (128 bits )
Hope this helps Russ
