Yes, please read about them in the MetaEditor help file.

I had already looked there and at first glance I saw no difference, so I asked here for it.
There doesn't appear to be much - except a default of 8 and a mistake in the documentation 'int value'?

There is no difference, to 2 functions are exactly the same. Only documentation is different.

   Print("double To String(120.0 + M_PI) : ",DoubleToString(120.0+M_PI)," <=> ",DoubleToStr(120.0+M_PI));
   Print("double To String(120.0 + M_PI,16) : ",DoubleToString(120.0+M_PI,16)," <=> ",DoubleToStr(120.0+M_PI,16));
   Print("double To String(120.0 + M_PI,-16) : ",DoubleToString(120.0+M_PI,-16)," <=> ",DoubleToStr(120.0+M_PI,-16));
   Print("double To String(120.0 + M_PI,-1) : ",DoubleToString(120.0+M_PI,-1)," <=> ",DoubleToStr(120.0+M_PI,-1));
   Print("double To String(120.0 + M_PI,-20) : ",DoubleToString(120.0+M_PI,-20)," <=> ",DoubleToStr(120.0+M_PI,-20));

Is there a reason for two identical functions? Which would be the best choice for the future?

Probably the new one.

One is for backwards compatibility with old mql4 the other for compatibility with mql5.
Sorry for reopening this thread, but I think it needs to be clarified. They have a difference on the decimal digits allowed. DoubleToStr allows up to 8 digits, meanwhile DoubleToString allows up to 16 decimal digits
