Detailed Description

Enables conversion of the object to either Int, Float, or Bool type.

An object which implements IIntObject will typically also implement IConvertible, which allows conversion to other types.

Example:

IIntObject* intObj = ...;
IConvertible* conv;
auto errCode = intObj.queryInterface(IConvertible::Id, reinterpret_cast<void**>(&conv));
if (OPENDAQ_FAILED(errCode))
  return;
 
Float val;
errCode = conv->toFloat(&val);
if (OPENDAQ_FAILED(errCode))
  return;
 
// print val
