Method

longtrunc(double value)
Truncates the specified value. 
return (long) value;
doubletrunc(double value, double threshold)
trunc 
return Math.max(Math.min(value, threshold), -threshold);
doubletrunc(double value, int dp)
Truncates a double to given decimal digits 
double factor;
factor = Math.pow(10, dp);
return Math.floor(value * factor) / factor;
doubletrunc(double value, int len)
trunc 
if (Double.isNaN(value)) {
    return Double.NaN;
if (Double.isInfinite(value)) {
    return value;
double p = Math.pow(10, len);
if (value > 0) {
...
doubletrunc(double x)
Return the integer portion of a double as a double. 
long lx = (long) x;
return (double) lx;
doubletrunc(double x)
trunc 
return x - x % 1;
doubletrunc(double x, double y)
Truncate x down to the nearest y. 
return y * Math.floor((x + .00001) / y);
doubletrunc4(Double number)
trunc 
return Math.round(number * Math.pow(10, 4)) / Math.pow(10, 4);
doubletruncate(double d)
truncate 
if (d < 0)
    return -1 * Math.floor(d * -1);
else
    return Math.floor(d);
doubletruncate(double fullVal, int digits)
Given a double, zeros all portions of the fraction past a given number of digits. 
double factor = Math.pow(10.0, (double) digits);
int itmp = (int) (factor * fullVal);
return ((double) itmp) / factor;
