Description

The list of methods to do Double Number Truncate are organized into topic(s).

Method

doubletruncate(double oldVal, double newMin, double newMax)
truncate 
double retVal = oldVal;
if (retVal < newMin) {
    retVal = newMin;
if (retVal > newMax) {
    retVal = newMax;
return retVal;
...
doubletruncate(double value, double precision)
Utility method used to truncate a double to the given precision. 
double result;
precision = Math.pow(10, precision);
if (value > 0) {
    result = Math.floor(value * precision) / precision;
} else {
    result = Math.ceil(value * precision) / precision;
return result;
...
doubletruncate(double value, int precision)
truncate 
String str = Double.toString(value);
String precisionstr = str.substring(str.indexOf('.') + 1);
if (precisionstr.length() <= precision) {
    return value;
} else {
    long tmp = Math.round(value * Math.pow(10, precisionstr.length()));
    for (int i = 0; i < precisionstr.length() - precision - 1; i++) {
        tmp /= 10;
...
doubletruncate(double value, int truncation)
truncate 
return Math.floor(value * truncation) / truncation;
inttruncate(double x)
truncate 
int res;
if (x > 255)
    res = 255;
else if (x < 0)
    res = 0;
else
    res = (int) x;
return res;
...
doubletruncate(double x)
Returns the value of the integer of highest magnitude (farthest from zero) whose absolute value is at most that of x. 
return x > 0.0 ? Math.floor(x) : Math.ceil(x);
doubletruncate(double x, double gran)
truncate 
return Math.round(x / gran) * gran;
double[]truncate(double[] arr, int m)
truncate 
double[] tArr = new double[m];
System.arraycopy(arr, 0, tArr, 0, m);
return tArr;
doubletruncate(final double value, final double min, final double max)
truncate 
return Math.min(Math.max(value, min), max);
doubletruncate(final double value, final double precision)
Truncate a value to the specified precision. 
double f, v;
boolean b;
if (precision <= 0.0d)
    return value;
if (value == 0.0d)
    return 0.0d;
if (value < 0.0d) {
    v = -value;
