Grade calculations are an alternative to 'weightings' which can be seen in this image. To set the 'Aggregation' to use weights, click the 'Edit' button at the category level and choose edit settings. Then make sure 'Weighted Mean of Grades' is selected and you will be able to manually set the weights. See

To create a 'Grade calculation' for a category total, click 'Edit' and 'Edit calculation'

Tip

Grade values in the Myplace Gradebook will retain a value which is defined to 5 decimal places. Even if you set the value to display to less decimal places, if that value is involved in calculating anything e.g. a class total, the '5 decimal place value' will be used in that calculation, which can cause confusion.

The only way to 'round' in real value terms, if required, is to use a Grade Calculation. See

Moodledocs

DisplayText	Calculation functions
Name	Grade_calculations#Calculation_functions

to see the correct term to use for this.

This will take you to the 'Grade Calculation' screen which will allow you to create precise and complex calculations using items in you Gradebook.

Warning

Please be aware that if an assignment or quiz is deleted/recreated in a Myplace class, this will 'break' any gradebook calculation. As one of the items will appear missing to the calculation, Myplace (Moodle) attempts to solve the calculation and it causes much of the class page to run very slowly.

The main disadvantage to using Grade Calculations rather than 'weights' is that they are much less visible to other staff users of that class. Generally it's recommended to use 'weights' if it's possible to achieve the results you need using that and if using Grade Calculations, make sure that other staff are informed of this.
