Source Link

Document

Returns the largest (closest to positive infinity) double value that is less than or equal to the argument and is equal to a mathematical integer.

Usage

From source file:Coordinate.java

/**
 * The compareTo method compares the receiving object with the specified object and returns a 
 * negative integer, 0, or a positive integer depending on whether the receiving object is 
 * less than, equal to, or greater than the specified object.
 *
 * @param c the event to compare this one to
 *
 * @return  an integer indicating comparison result
 *///  www .  j  a  v  a2s. c  o m
public int compareTo(Coordinate c) {

    String me = this.getLatitudeAsString() + this.getLongitudeAsString();
    String you = c.getLatitudeAsString() + c.getLongitudeAsString();

    Double meDbl = Double.valueOf(me);
    Double youDbl = Double.valueOf(you);

    if (meDbl == youDbl) {
        return 0;
    } else {
        Double tmp = Math.floor(meDbl - youDbl);
        return tmp.intValue();
    }
