Hello Shaan!!

Nice work.
I have also tested Calculate version 46-1 with Ubuntu 20.04 sucrose package
version 0.117.
All the Errors are reproducible.

   1. Warning when attempting to calculate and expression ( pressing ‘=’ )

   65535 = (Binary) 1111111111111111 = (Hexadecimal) FFFF


Gtk-WARNING **: 19:47:57.736: Don't know color 'Gdk.Color(red=6553
5, green=65535, blue=65535)'

*Workaround is to use Gdk.RGBA as Gdk.Color is deprecated and will not work
with newer versions of Ubuntu and Debian.*

1. Error when using ‘pi’ and ‘e’ in expression:

1593526849.741283 ERROR root: Internal error (<class
'UnboundLocalError'>): local variable
 'list' referenced before assignment
Traceback (most recent call last):
  File "/usr/share/sugar/activities/Calculate.activity/astparser.py",
line 674, in evaluat

    ret = self._process_node(eqn, state)
  File "/usr/share/sugar/activities/Calculate.activity/astparser.py",
line 444, in _proces

    return self._process_node(node.value, state)
  File "/usr/share/sugar/activities/Calculate.activity/astparser.py",
line 515, in _proces
s_node
    if node.id not in list(state.used_var_ofs.keys()):
UnboundLocalError: local variable 'list' referenced before assignment

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/share/sugar/activities/Calculate.activity/layout.py",
line 133, in <lambda>
    lambda w: self._parent.process()],

line 680, in evaluat
e
    raise ParseError(msg, 0)
TypeError: __init__() missing 1 required positional argument:
'eqn'Reproducible on Ubuntu 20.04


   1. Hovering over Algebraic, Trigonometric toolbar buttons throws:

with negative dimen
sions. Did you forget to allocate a size? (node menuitem owner

   1.

   Submitting trigonometric functions without values displays an error in
   the Activity but only the first character is highlighted red instead of the
   full function. -- Reproducible on Ubuntu 20.04
   2.

   Submitting logical expressions without values throws:

1593527432.306449 DEBUG Calculate: Result: ParseError('Parse error',
6, 'True!=')
Traceback (most recent call last):
  File "/usr/share/sugar/activities/Calculate.activity/layout.py",

line 75, in __str__
    msg = _("Error at '%(a)', position: %(b)") % \
ValueError: unsupported format character ''' (0x27) at index 14

*Reproducile on Ubuntu 20.04 -- We need to implement Exception handlers*


   1. Submitting / pressing ‘=’ without entering any value throws

1593527598.469328 DEBUG root: Parsing preprocessed equation: ''

  File "/usr/share/sugar/activities/Calculate.activity/layout.py",

    tree = self.parser.parse(s)
  File "/usr/share/sugar/activities/Calculate.activity/astparser.py",
line 656, in parse
    raise ParseError(msg)
TypeError: __init__() missing 2 required positional arguments: 'start'
and 'eqn'*Reproducile on Ubuntu 20.04 -- We need to implement
Exception handlers*


I will now move forward with solving these errors and opening issues.
Thanks
