Hi *,
I need store result of floating point calculation (in my example
arctan()) in memory pointed by some variable. See this code:
var a: single; pa: PSingle;
asm
fild dy
fild dx
fpatan
fstp a
fwait
end;
pa^ := a;
It works, but is there any way how to store

Well, no, there was no unit, rather a version of Turbo Pascal 3.0x had a
version that natively used BCD math for "reals" instead of the 6byte
REAL type, just as there was a x87 version that used hardware x87 FP
(IEEE754) fl

At least in FPC modes they can use inheritance to solve this (see below) or
by putting their units after the

Sven, multiple helpers would be greatly appreciated, especially considering

Here is another example:
type
TDay = (Monday = 0, Tuesday, Wednesday, Thursday, Friday, Saturday,
Sunday);
TDayHelper = record helper for TDay
function AsByte: Byte;
function ToString: string;
end;
function TDayHelper.AsByte: Byte;
begin
Result := Ord(Self);
end;
function TDayHe
Marco, it doesn't work that way.
Type helpers simply allow you to extend an existing type with new methods
and/or properties. When you declare a type helper you extend all instances
of said type given that:
A) You 'use' the unit declaring the type helper in some other unit.
B) No other unit you'r

Good job and thank you Sven!
I'm having trouble understanding why this could be useful (apart from
completeness).
The only thing I can come up with is a
If your header looks enough like IDL (which is essentially C++ with
annotations), you may also be able to use one of the available IDL compilers.
There are a few dialect issues though, so YMMV. I'd say MPFR has a few defines
too many for my idlproc (https://github.com/martok/idlproc), but may come
I'm using Chelper. (http://wiki.freepascal.org/Chelper)
It's my choice, because it preserves comments (which is usually an
important part of open-source libs)
plus, can be configured to handle library header-specific defines.
Naturally, the process is semi-automatic, but get be done quite quick
