Does anyone out there know how to convert an integer to a longreal in modula2 (obviously). Thanks in advance....

Does anyone out there know how to convert an integer to a longreal (in modula2 ofcourse). Thanks,

Try looking at the VAL procedure. In TopSpeed it would be something like this: i: INTEGER; x: LONGREAL; .... x:= VAL(LONGREAL, i); Of course some other version may (prob'ly will) do it differently. You might also check the FLOAT procedure (in the "standard" (3th ed) it's for converting CARDINAL to REAL). Greg

Greg, Thanks for the information on the integer to longreal conversion in modula2. Not sure if it worked yet (am getting this info for a friend) but I will tell you if it did. Thanks, Barry cs419110@pc.usl.edu(definitly works) bpd5428@rouge.usl.edu(having problems with this account)

And ISO M-2 may do away with LONGREALs anyway. -------------------------------------------------------------------------------- Robert L Barton bartonr@eecs.cs.pdx.edu Concert Concessions Corporation, a division of Winterland Productions

As to standards, well sometimes what works is more useful than what is standard. I found no reference to LONGREALs in N Wirth's 3th ed of PIM2 and I don't know much about the ISO M2 work (cept it's not finished). If it were up to me I would do things differently, but it's not.... (I really don't care for all that type casting and explict conversion, wish someone would expand "the standard" (what ever it is) to include operator overloading then I overload '+' to add int's to card's or card's to real's or ... apples to oranges <grin>) Greg

It's very simple:
VAR i:INTEGER;
l:LONGREAL;
...
i:=10; (* e.g. *)
l:=LONGREAL(i);
^^^^^^^^^^^^^^^
