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:Util.java

public static double mod(double x, double y) {
    double m = x;
    if (y != 0) {
        m = x - y * Math.floor(x / y);
    }/*w w w .  j a v  a2 s . c  o m*/
    return m;
}

    int e5Longitude = (int) Math.floor(point[1] * 1e5);

    int differenceLatitude = e5Latitude - context.previousLatitude;
    int differenceLongitude = e5Longitude - context.previousLongitude;

    context.previousLatitude = e5Latitude;
    context.previousLongitude = e5Longitude;

    String encodedLatitude = encodeSignedNumber(differenceLatitude);
    String encodedLongitude = encodeSignedNumber(differenceLongitude);
