# IsCurrencyNumber

## Declaration

`Function IsCurrencyNumber( const S : string) : Boolean`

### Example

```pascal
procedure OnMapEvent(var Value:Variant);
begin
  Value := IsCurrencyNumber('abc123'); //returns false
Value := IsCurrencyNumber('$1,230.00'); //returns true.
Value := IsCurrencyNumber('1230'); //returns true.
end;
```

## Description

Returns True or False depending on whether the input string contains only numeric characters or currency format symbols. If this function returns True then you can safely use a [Conversion](/flow/guide/scripting-reference/functions/conversion/) function on it to turn it into a numeric data type.

This function allows for currency symbols defined within the computers regional settings.

Refer [IsDigit](/flow/guide/scripting-reference/functions/numeric/isdigit) for a function that checks only the first character to see if it is a digit. Refer to [IsNumber](/flow/guide/scripting-reference/functions/numeric/isnumber) for a function that checks if the string contains only numbers without currency formatting.
