Method Detail

exponentiate

public static long exponentiate(int iBbase,
                                int iExponent)
                         throws java.lang.IllegalArgumentException

Method to make Exponention

Parameters:

iBbase - - base of Exponention [1..]

iExponent - - exponent of Exponention [0..14]

Returns:

long - result of Exponention

Throws:

java.lang.IllegalArgumentException - - in case of arguments out of valid range

getDigitNumberString

public static java.lang.String getDigitNumberString(int iInputNumber,
                                                    int iDigitLength)

Method to make specified length digit number string representation from particular input number. For example, if there will be send input number 32 and digit lenhth = 8, output will be string '00000032'

Parameters:

iInputNumber - - input number that will be converted into 8 digit number string representation

iDigitLength - - length of the output digit number string

Returns:

String - digit number string representation
