ptvalue 0.2.0

• Multiplication and division between a ptvalue() and a double/integer value is now allowed.
  • The output is kept as a ptvalue() for now.
  • Multiplication and division of a ptvalue() with a negative value are still not allowed and will raises an error.
  • If multiplication and division with a negative value is needed, ptvalue() can be converted back to double values with unclass() or as.double().
  • Test unit have been added.
• Other helper functions have been added in addition to invert_sign():
  • abs_sign() converts values to values with an ‘absolute’ sign (times or div)
  • as_times() converts values to times only
  • as_div() converts values to div only
  • Documentation for these four functions have been added and grouped into a single page.
  • Test units have been added.
• More details were added in README:
  • About div() and times(), for creating directly PT values.
  • About abs_sign(), as_times(), and as_div()
