What is the example of truncation error?
Suppose you want to calculate the area of a circle with a radius of 10 cm.If you use pi = 3.14 the area will be calculated as 314 cm^2if, instead, you use pi = 3.145159, the area will be 314.5159 cm^2if you use pi, as used by Excel on my computer, you will get 314.159265358979 cm^2.If you use the most accurate value of pi (currently around 10 trillion digits) you will get a more accurate value of the area.The difference between the calculated value and the true value is the truncation value.
