Description

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

Method

intpow(int number, int power)
pow 
int result = 1;
for (int i = 0; i < power; ++i)
    result *= number;
return result;
intpow(int value, int exp)
pow 
return value == 2 ? 1 << exp : (int) Math.pow(value, exp);
intpow(int x, int y)
Positive integer powers. 
if ((x >= 0) && (x < 50) && (y < 50)) {
    return INTEGER_POWERS[x][y];
} else {
    switch (y) {
    case 0:
        return 1;
    case 1:
        return x;
...
voidpow(int[] arr, double p)
POW all elements of the specified primitive type array. 
for (int i = 0, l = arr.length; i < l; i++) {
    arr[i] = (int) Math.pow(arr[i], p);
doublepow(Integer a, Integer b)
Pow. 
return Math.pow(a.doubleValue(), b.doubleValue());
longpow(long base, long exp)
Convenience method to calculate the power. 
return (long) Math.pow(base, exp);
longpow(long n, long pow)
pow 
if (pow == 0) {
    return 1;
long retval = n;
for (long i = 2; i <= pow; i++) {
    retval *= n;
return retval;
...
longpow(long value, long pow)
pow 
long tmpValue = 1;
for (int i = 0; i < pow; i++) {
    tmpValue *= value;
return tmpValue;
doublepow(Number x, Number exponent)
pow 
return Math.pow(x.doubleValue(), exponent.doubleValue());
Stringpow(String str, int n)
Power-function in the free Monoid over Characters (AKA "Strings"). 
StringBuilder b = new StringBuilder();
for (int i = 0; i < n; i++) {
    b.append(str);
return b.toString();
