iHigh returns rounded number.

New comment
 

When getting a value of the last daily bar using iHigh it returns only rounded number and I need all digits for precision.

double high = iHigh(NULL,PERIOD_D1,1); returns 1.329 while the high is 1.32899

 I cannot use DoubleToStr as I need the value as "double" for further processing.

Any idea how to get all digits?

It happens already,  what makes you think you are getting a rounded value ?  how are you seeing this value ?  show your code.

I use

double high = iHigh(NULL,PERIOD_D1,1); 

Alert (high);

 

yesterday EURUSD high was  1.32899 but Alert window shows 1.329.

void Alert( ...)
Data of double type output with 4 decimal digits after point. To output with more precision use DoubleToStr() function.

Yep,  but shouldn't that show 1.3289  ?  not 1.329 ?

I have a different high for yesterday,  can you try this please and let us know what you get.

double high = iHigh(NULL,PERIOD_D1,1); 

Alert ("High - string ", DoubleToStr(high, Digits) );   //  Edit,  sorry, should have included Digits
 
I see, thanks! I fought I was going crazy. So the "high" value is correct after all. Didn't know about Alert limitations.

The double was 1.32899     then it is not 1.3289  but  1.3290  

we see if last digit is o then the last digit is not printed in Alert

You can check

   double high = 1.32899;
//----
   Alert(high);

I did,  I knew Alert, Print and Comment all just print a maximum of 4 digits,  I didn't know they also rounded values up.

OK,  so the 4 digit treatment is not a truncation as I assumed it is in fact a rounding ?  Thanks,  something else I have learned today :-)
