Count Decimal on Crystal Report

 Try This !

numbervar x:= abs({table.field});


stringvar y:= strreverse(totext(x,10,""));
numbervar z:= tonumber(y);
numbervar c:= len(totext(z,0,""));


Example: 


Suppose Price is 0.1023000 


strreverse(totext({Price},7))       ==>     0003201.0
tonumber( 0003201.0 )               ==>     3201.0
Round(tonumber( 3201.0 ))           ==>     3201
len(totext(  3201  ,0))             ==>     4  ,

so set decimal places to 4
