with NormalizeDouble it only return

What are you trying to do here,
please post your code here and use alt+s
such that we
see it like this
There is no such thing as a long double. A long is Long, a double is double, a long can not be a double. Study the concept data types.
thank you for reply i meant long as large some of digits not long as data type
Show all the relevant code if you need coding help.
for some reason when i try this code
void OnTick() { double Ask=NormalizeDouble(SymbolInfoDouble(NULL,SYMBOL_ASK),_Digits); double Bid=NormalizeDouble(SymbolInfoDouble(NULL,SYMBOL_BID),_Digits); double Spread=Ask-Bid*_Point; Print(Spread); Print(NormalizeDouble(Spread,0)); }
first print give me this
2020.02.07 22:05:02.297 Calling_Functions (EURUSD,M1) 2.999999999997449e-10
second line give me this
2020.02.07 22:05:06.829 Calling_Functions (EURUSD,M1) 0
double Spread=Ask-Bid*_Point;
Why are you doing this?
Maybe you mean
double Spread=(Ask-Bid)*_Point;
or maybe
double Spread=(Ask-Bid)/_Point;
or
double Spread=Ask-Bid;
Why are you doing this?
Maybe you mean
or maybe
or
ah i forgot the ()
tnX something so easy yet forgot it :)
Thank you

So what was your intention?
If it was
double Spread=(Ask-Bid)*_Point;
Why multiply by Point?

I think this is what he was after:
int spread = SymbolInfoInteger(_Symbol,SYMBOL_SPREAD);
Print(NormalizeDouble(Spread,0));This will always result in zero. You used NormalizeDouble, It's use is usually wrong, as it is in your case.

Floating point has infinite number of decimals,
it's your not understanding floating point and that some numbers can't be represented exactly. (like 1/10.)
Double-precision floating-point format - Wikipedia, the free encyclopedia - Print out your values to the precision you want with DoubleToString - Conversion Functions - MQL4 Reference.
- SL/TP (stops) need to be normalized to tick size (not Point.) (On 5Digit Broker Stops are only allowed to be placed on full pip values. How to find out in mql? - MQL4 programming forum) and abide by the limits Requirements and Limitations in Making Trades - Appendixes - MQL4 Tutorial and that requires understanding floating point equality Can price != price ? - MQL4 programming forum
- Open price for pending orders need to be adjusted. On Currencies, Point == TickSize, so you will get the same answer, but it won't work on Metals. So do it right: Trailing Bar Entry EA - MQL4 programming forum or Bid/Ask: (No Need) to use NormalizeDouble in OrderSend - MQL4 programming forum
- Lot size must also be adjusted to a multiple of LotStep and check against min and max. If that is not a power of 1/10 then NormalizeDouble is wrong. Do it right.
- MathRound() and NormalizeDouble() are rounding in a different way. Make it explicit.

since Spread removed from MQL5 and helpfile mentioned this method
double Spread=Ask-Bid;
but when i try to trim it from something like this

i tried other Mathematical function same results
even turn it to INT doesnt help either
the only method is working turn it to string then return it standard int or less digits double
is it bugged or what?!
