calculation - Why do I get different results from Python Interpreter (2.7.6) and a calculator? -


i have following formula:

szt = sz0 + (((sz1 - sz0) / (wmz1 - wmz0)) * (wmzt - wmz0))

example:

86266 + (((168480 - 86266) / (703786 - 510531)) * (703765.0 - 510531))

when use python interpreter (2.7.6) calculation, got result:

86266

when use calculator (google example) got result:

168471.066239

i assume second correct result.

what's wrong calculation in python?

basically python 2.7 , 3.3 calculations different each other.

python 3.3 return 0.1 1/10, while python 2.7 return 0. can enable new division operator using __future__

>>> __future__ import division >>> print(86266 + (((168480 - 86266) / (703786 - 510531)) * (703765.0 - 510531))) 168471.066239

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
