Usage

From source file:StringUtil.java

/**
 * Takes a double and turns it into a percent string.
 * Ex.  0.5 turns into 50%/*  w  w  w  .j a v a  2 s .com*/
 * 
 * @param value
 * @return corresponding percent string
 */
public static String getPercentValue(double value) {
    //moved from HTMLReport.getPercentValue()
    value = Math.floor(value * 100) / 100; //to represent 199 covered lines from 200 as 99% covered, not 100 %
