I'm struggling to get my head around the difference between Accuracy[] and Precision[], and similarly AccuracyGoal[] and PrecisionGoal[]. I'm writing a small optimisation package at the moment, and would like my options to be similar to those of FindMinimum[], but can't sort out the difference. I get the same answer for Accuracy[1] as Precision[1], and for Accuracy[1.] as Precision[1.], and for Accuracy[1.000000000000000000000000000000000001] as Precision[1.000000000000000000000000000000000001]. I'm afraid the accuracy of my brain is unable to cope. Help! Paul. (Accurate and Precise answers most welcome)
