# Controlling Digits output for same numbers used but different outputs

I am a teacher how is working with sagetex to automate some worksheets to save some time on creating different versions.

In my worksheets students are given numbers to 2 or 3 digits of accuracy, but later there is a solution guide attached, and I would like to change the level of accuracy. An example: 2.5 times 350 equals 875, but rounded to 2 digits is 880. I would like to change the accuracy of the solutions produced.

I am still very new to all this, and would love any advice or help.

Your links don't work. You should write any relevant code here instead. Do I understand correctly that for

`x = 875`

and`digits_accuracy = 2`

you want to obtain`round(x/10^(len(str(x))-digits_accuracy))*10^(len(str(x))-digits_accuracy)`

?
