Description

The list of methods to do Integer to are organized into topic(s).

Method

intintToPrefixCoded(final int val, final int shift, final char[] buffer)
Expert: Returns prefix coded bits after reducing the precision by shift bits. 
if (shift > 31 || shift < 0)
    throw new IllegalArgumentException("Illegal shift value, must be 0..31");
int nChars = (31 - shift) / 7 + 1, len = nChars + 1;
buffer[0] = (char) (SHIFT_START_INT + shift);
int sortableBits = val ^ 0x80000000;
sortableBits >>>= shift;
while (nChars >= 1) {
    buffer[nChars--] = (char) (sortableBits & 0x7f);
...
byte[]intToRegisters(int v)
Converts an int value to a byte[4] array. 
byte[] registers = new byte[4];
registers[0] = (byte) (0xff & (v >> 24));
registers[1] = (byte) (0xff & (v >> 16));
registers[2] = (byte) (0xff & (v >> 8));
registers[3] = (byte) (0xff & v);
return registers;
float[]intToRGB(int color)
int To RGB 
float[] rgb = new float[3];
long blue = color % 256;
color = color / 256;
long green = color % 256;
color = color / 256;
long red = color % 256;
rgb[0] = red / 255F;
rgb[1] = green / 255F;
...
int[]IntToRGB(int rgbInt)
Converts an RGB integer value into an array of RGB values. 
int r = (int) (rgbInt / 256.0 / 256.0 % 256);
int g = (int) (rgbInt / 256.0 % 256);
int b = (int) (rgbInt % 256);
return new int[] { r, g, b };
int[]intToRgbComponents(int rgb)
Convert rgb to its components 
return new int[] { rgb >> 16 & 0xFF, rgb >> 8 & 0xFF, rgb & 0xFF };
StringintToRoman(int i)
set command line for Runtime.exec() depending on operation system R_BATCH is set in chg.properties and loaded with programm start R_BATCH contains absolute pathname to batch file inside the batchfile R batch is called 
if (i > 50) {
    return intToRoman(i - 50);
String roman = "";
if (i >= 10) {
    for (int j = (int) Math.ceil(i / 10); j > 0; j--) {
        i -= 10;
        roman += "X";
...
StringintToRoman(int value)
int To Roman 
if (value <= 0 && value >= 4000) {
    return null;
String romanString = "";
int remainder = value;
for (int i = 0; i < BASIC_VALUES.length; i++) {
    while (remainder >= BASIC_VALUES[i]) {
        romanString += BASIC_ROMAN_NUMBERS[i];
...
StringintToScaleString(final int number, final int scale)
int to scale string 
if (number < 0) {
    throw new RuntimeException(String.format("unsupport nagative number:%s", number));
int length = scale <= characters.length ? scale : characters.length;
StringBuilder builder = new StringBuilder();
int num = number;
do {
    int mod = num % length;
...
ShortintToShort(final int value)
int To Short 
return (short) value;
intintToSlider(final int min, final int max, final int value)
Converts the integer value to a slider selection. 
return doubleToSlider(min, max, value);
