Well, hmm, yes, this is what I actually use, and it works pretty well. I
didn't want to use it in the first place (the dark side of the force is
always tempting ;), but I must admit that it was a mistake.
Thanks a lot for the quick answer.

Value.stringValue() will convert almost any kind of Value to a String,
including floats, so why not use it?
public String stringValue(Context c) throws JessException
{
switch (m_type)
{
case RU.ATOM:
case RU.STRING:
case RU.VARIABLE:
case RU.MULTIVARIABLE:
case RU.SLOT:
case RU.MULTISLOT:
return (String) m_objectval;
case RU.INTEGER:
return String.valueOf(m_intval);
case RU.FLOAT:
return String.valueOf(m_floatval);
case RU.EXTERNAL_ADDRESS:
return m_objectval.toString();
default:
throw typeError("stringValue", "Not a string");
}
}
The string produced by Value.toString() is meant to be suitable for
writing out to a file and later reparsed; it's employed during
save-facts, for example.
