Actually the word you mean is precision. This refers to the exactness of 
a number, generally, how many decimal places are displayed. Accuracy 
refers to the correctness of a number. If your program gives 12 as a 
result for PI, it is hopelessly inaccurate. 

In any case, as far as calculating PI in a test program, why not 
approximate it by selecting random numbers in a square and determining 
the proportion of them that lie in an arc of the radius of your square 
width. You could actually have an accuracy input to specify how many 
random numbers to generate for the calculation.

I'm a stickler for grammar rules.
