Hi
When I run next floattest program
program floattest;
uses sysutils;
var a,b,c:double;
begin
a:=0.5;
b:=0.3;
writeln(format('%5.3f',[a*b]));
a:=-0.5;
c:=a*b;
writeln(format('%5.3f',[c]));
end.
I received this output:
===================== output =================================
0.150
An unhandled exception occurred at $0000D550 :

===================== output =================================
if I change from double to single I obtain the same output, Is single
implemented as double?
