Round digit (MQL4)

[Lee Su Keat]

Hi there, 

Is there anyway to round 0.001 to 0.01? 

Eg : 0.012 to 0.02. 

I tried round (); 

Unfortunately it only round up 5 and above. 

Thanks in advance.

Hi and good morning,

in my opinion there is no MQL function for your requirement. But you can
use MathCeil() for that. E.g. (for 2 digits):

value = MathCeil(value * 100.0) / 100.0;

Best regards

Yes, use ceil() / MathCeil(). There is round(), floor() and ceil(). It helps to read the documentation ... https://www.mql5.com/en/docs/math

Example:

double
   dblValue   = 0.012,
   dblCeiling = ceil( dblValue / 0.01 ) * 0.01;

PrintFormat("Value = %f; Ceilling = %f", dblValue, dblCeiling);
