Units handling in numerical and calculated questions with summation factor

by Juan V. Conde - Thursday, January 23, 2020, 5:45 PM

Hi:

Usually the units handling in numerical and calculated questions works with a multiplier factor, like is exposed here https://docs.moodle.org/38/en/Calculated_question_type#Question_set-up (15). But sometimes, the factor could be a summation factor (logarithm units), like handling decibels: 0 dBW is equal to 0dBW + 30 dB = 30 dBm. Here, the factor from dB to dBm is +30. ¿Any idea to manage this? ¿It would be a improvement in question bank roadmap?

Thank you!

Hello Juan,

Usually the units handling in numerical and calculated questions works with a multiplier factor...

I think with these questions, units handling "only" works with a multiplier factor. Unfortunately, with the Formulas question, unit handling also only works with a multiplier factor.

This is somewhat surprising since dBW, dBm, etc. are often used in acoustics, electronics, telecommunications and control theory.

Any idea to manage this?

The ideal would be to modify the source code of the question.
