Invalid Decimal Format

Edit online

C language only In ILE C, packed decimal is implemented as a native data type. This allows an error such as invalid decimal format to be detected at compile time.

In C++, detection of a similar error is deferred until runtime, as shown in the following examples:

#define _DEBUG 1

#include <bcd.h>

int main ( void )
{
 _DecimalT<10,20> b= __D("ABC"); // Runtime exception is raised
}

and

#define _DEBUG 1

#include <bcd.h>

int main ( void )
{
  _DecimalT<33,2> a;            // Max. dig. allow is 31. Again,
                               // runtime exception is raised
}

Note: Some errors can be detected at compile time, for example: n<1, (_Decimal<-33,2>).
