If the question author tries to set the required precision for a number entry part to a negative number of decimal places or sig figs, throw an error.

Hi,
Thanks for offering. I think you just need to duplicate the test at https://github.com/numbas/Numbas/blob/master/runtime/scripts/parts/numberentry.js#L132 and throw an error when precisionType=="dp" && precision<0.
See our page on contributing to Numbas for information on how to set up a development environment.
