Identifying the value of the decimal number

[FrKal]

Hi,

can you please advise me how to program EA to identify the value of just specified decimal?

For example Identify 1.43200 as x.xxx00 (something like "LastTwoAreZeros == true").

The only thing I came with is list all the values I want (for example "if Price = 1.43200 || 1.43300 || 1.43100" etc.) but is there a more automated option?

Thank you for the answers.

if (NormalizeDouble(Bid,_Digits) == NormalizeDouble(Bid,3))

FrKal: can you please advise me how to program EA to identify the value of just specified decimal? For example Identify 1.43200 as x.xxx00 (something like "LastTwoAreZeros == true").	Round price to the nearest 10 pips MT4:NormalizeDouble - General - MQL5 programming forum Then see how close price is to it. Doubles are rarely equal. The == operand. - MQL4 forum
Taras Slobodyanik: if (NormalizeDouble(Bid,_Digits) == NormalizeDouble(Bid,3))	Doubles are rarely equal. The == operand. - MQL4 forum Do NOT use NormalizeDouble, EVER. For ANY Reason. It's a kludge, don't use it. It's use is always wrong 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 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 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 forum or Bid/Ask: (No Need) to use NormalizeDouble in OrderSend - MQL4 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.

Show me where it is written in the documentation for MT4 - MT5.
And then I will follow your advice.

Doubles are rarely equal.

Yes you are right.

@ Taras Slobodyanik: Thank you, it looks very logical, I do not know why I did not see it.

@ whroeder1: Thank you as well. I get your point but have trouble with understand it (MathNearest and such). I will study your comment and try it and hope I will. Thank you, you push me up.
