2733982 - Function: ToNumber, returns different results in Crystal Reports depending on the Regional Settings


  • Incorrect numbers.
  • Numeric values are different, depending on the computer regional settings, when converting string to numbers in Crystal Reports.
  • The function: ToNumber ignores decimal places in Crystal Reports, when the Product Locale is set to some European countries.

Reproducing the Issue

  1. In Crystal Reports, create a report based on a database that contains numeric values stored in a string field.
  2. Create a formula to convert the string to a number, like:

       ToNumber ("1.45")
  3. Insert the formula on the report.
  4. Set the Product Locale to a country like: Italy
  5. Notice the formula returns the number: 145, instead of the expected number 1.45 


  • In many European countries, dot is not used as a decimal separator. The decimal separator used is a comma, and therefore if the values stored in the database contains dots, then it will be seen as thousand separators in some countries, and this is why the values converted to a number is different depending on the Regional Setting of the local computer.


  • When the numeric string contains decimals separators, then to be able to convert the string to a number regardless of the regional setting, create a formula like:

Local StringVar stringValue := <Database Field Name>;  // Insert your numeric field stored in text format here.

Local StringVar decimalSeparator := ".";
Local StringVar integerValue := "0";
Local StringVar fractionalValue := "0";
Local NumberVar numericValue := 0;

If decimalSeparator in stringValue Then
     integerValue := Split(stringValue,decimalSeparator)[1];
     fractionalValue := Split(stringValue,decimalSeparator)[2];
     integerValue := stringValue;

If isNumeric(fractionalValue) Then
     NumericValue := (ToNumber(fractionalValue)) / ToNumber("1" + ReplicateString("0",Length(fractionalValue)));

If isNumeric(integerValue) Then
     numericValue := numericValue + ToNumber(integerValue);
