double _high = iHigh(Symbol(), Period(), 0);
double _low = iLow(Symbol(), Period(), 0);
double result = _high - _low;
Excuse my limited English.
The type of result is a
double
number, and I want to convert the double number to an integer number, but the number of digits after the decimal point of the result corresponding to each symbol is uncertain.
I really don't know what to do other than doing it differently depending on the symbol.

Q :
"How to convert the value of iHigh() - iLow() to integer?... doing it differently depending on the symbol."
A :
Yes, we need to do it differently, depending on each the symbol.
Something like this may be a way to handle this :
...
int iSymbolSpecificDIGITs = SymbolInfoInteger( Symbol(), /* here, or
OrderSymbol(), if looping OrderBook */
SYMBOL_DIGITS
);
...
int iHiLoDIFF = (int)( MathPow( 10, iSymbolSpecificDIGITs ) * _high )
- (int)( MathPow( 10, iSymbolSpecificDIGITs ) * _low );

Main thing is to add NomalizeDouble to the result and add Digits in the bracket to sum everything up:
Alert(NormalizeDouble(result,Digits));
Or
Print("result:" + NormalizeDouble(result,Digits));
