It wasn't quietly banned. But quite openly, after two warnings. This is a decent forum for serious people. Your vast knowledge is worthless if you cannot convey it in your native (hopefully not Albanianspeak) language.
Read it all!
Many times!
Different branches.
But I still haven't seen a summary. I would like specifics and clarity on this issue.
Gentlemen, please, if it's not a bummer, make a final conclusion (about this) -
to all, users, losers, dummies, samovars - when comparing numbers of type double we use the following:
stdlib, bool CompareDoubles(double number1,double number2);
or
if (NormalizeDouble((a-b)>0,Digits)) {...}
or
int ComparePrice(double a, double b)
{
a -= b;
b = Point / 2;
if (a > b) return (1);
if (a < -b) return (-1);
return (0);
}
or
double a;
double b;
int factor = MathRound( MathPow(10, digits) ); // digits is the accuracy to be compared
If we compare prices, this is the predefined variable Digits
...
if (MathRound( (a - b) * factor ) != 0)
{
... // a != b
}
if (MathRound( (a - b) * factor ) == 0)
{
... // a == b
}
if (MathRound( (a - b) * factor ) > 0)
{
... // a > b
}
if (MathRound( (a - b) * factor ) < 0)
{
... // a < b
}
or
When comparing double-type numbers with accuracy of up to 4-5 digits, you don't have to elaborate any more.
