问题 How do I get the stationarity test from the fractal package in R to not print any output to the screen. For example, with the shapiro.wilk test when setting the result as a variable it does not give any output as follows lg.day.ret.vec <- rnorm(100, mean = 5, sd = 3) shap.p <- shapiro.test(lg.day.ret.vec)$p.value This is the case for most tests but when I do it for the stationarity test I get some output in the r console. library(fractal) stat.p <- attr(stationarity(lg.day.ret.vec),"pvals")[1

问题 in my code i use integers multiplied by 100 as decimals (0.1 is 10 etc). Can you help me to format output to show it as decimal? 回答1: int x = 100; DecimalFormat df = new DecimalFormat("#.00"); // Set your desired format here. System.out.println(df.format(x/100.0)); 回答2: I would say to use 0.00 as format: int myNumber = 10; DecimalFormat format = new DecimalFormat("0.00"); System.out.println(format.format(myNumber)); It will print like: 10.00 The advantage here is: If you do like: double
