Decimals/Numerics that are stored as 64-bit integers always display as xxx.2.

The following should fix the problem:

Original code (on or about line 1782):

val->value.str.len = sprintf(string_data, "%Ld.%0*Ld",
     (ISC_INT64) (*((ISC_INT64 *)data) /
     (int) pow(10.0, (double) -scale)),
     -scale,
     (ISC_INT64) abs((int) (*((ISC_INT64 *)data) %
     (int) pow(10.0, (double) -scale))));

Change to:
val->value.str.len = sprintf(string_data, "%Ld",
     (ISC_INT64) (*((ISC_INT64 *)data) /
     (int) pow(10.0, (double) -scale)));
val->value.str.len += sprintf(string_data +
     val->value.str.len, ".%0*Ld",
     -scale,
    (ISC_INT64) abs((int) (*((ISC_INT64 *)data) %
    (int) pow(10.0, (double) -scale))));



The problem is with MSVC++.  It doesn't seem to like two int64s in the same sprintf statement.  I don't yet have all the pieces to compile the extension so I have not fully tested it, but I have duplicated the problem in a test program and verified that the above code fixes the problem in the test program.

This is also reported as #13807

The original fix I posted has its own bug (due to me not VC++) when the number is less than 0 but greater than -1 the negative sign does not appear.  This fixes it (and the original problem also):
case SQL_INT64:
tv64 = (ISC_INT64) *((ISC_INT64 *) data);
			iv64 = (tv64 / (int) pow(10.0, (double) -scale));
			fv64 = (ISC_INT64) abs((int) tv64 % (int) pow(10.0, (double) -scale));
			val->type = IS_STRING;
			if ( tv64 < 0  &&  iv64 == 0 ) 
				val->value.str.len = sprintf(string_data, "-0");
			else
				val->value.str.len = sprintf(string_data, "%Ld", iv64);
			val->value.str.len += sprintf(string_data + val->value.str.len, ".%0*Ld", -scale, fv64);
			val->value.str.val = estrdup(string_data);
			break;

The original fix I posted has its own bug (due to me not VC++) when the number is less than 0 but greater than -1 the negative sign does not appear.  This fixes it (and the original problem also):
Add these declarations:
 ISC_INT64	tv64;
 ISC_INT64	iv64;
 ISC_INT64	fv64;

then change the code:

case SQL_INT64:
 tv64 = (ISC_INT64) *((ISC_INT64 *) data);
 iv64 = (tv64 / (int) pow(10.0, (double) -scale));
 fv64 = (ISC_INT64) abs((int) tv64
       % (int) pow(10.0, (double) -scale));
 val->type = IS_STRING;
 if ( tv64 < 0  &&  iv64 == 0 ) 
  val->value.str.len = sprintf(string_data, "-0");
 else
  val->value.str.len = sprintf(string_data, "%Ld", iv64);
 val->value.str.len += sprintf(string_data +
           val->value.str.len, ".%0*Ld", -scale, fv64);
 val->value.str.val = estrdup(string_data);
 break;

please make a patch against the current CVS version.

I think it must be already fixed in CVS.
Have a look at it and if you can try it on Win32.
