Rounding numbers in MT4 via NormalizeDouble - page 6

Roman Starinskij:

That's how it works! Thank you. I normalise to 3 digits and then trim the extra digits after the decimal point.

Can you tell me if there is a standard function to trim H digits after the decimal point? Like StringSubStr only if it is a fractional number.

Trimai.

extern ushort Characters_delete = 1;


////////////////////////////////////
string resoult="";  
string data=DoubleToString(Bid,Digits); 
int lenth=StringLen(data);


for(int i=0;i<lenth-Characters_delete;i++)
{
StringAdd(resoult,StringSubstr(data,i,1));
}
 
Vasyl Nosal:

Trimai.

Couldn't you come up with a more convoluted way?

The best way is to use DoubleToStr() with one extra character, and use StringSubstr() to discard the last character.

The code?

Couldn't have done any better. Lines are terribly slow.

There are special functions

Do it yourself.

That's what I thought.

What's there to laugh about. I wish there was something to do.

What code.

Multiply by a factor, take the minimum integer. divide by a factor

No, not that one. This one is"DoubleToStr() with one extra sign, and use StringSubstr() to discard the last sign".
