math.pow

Question

i have a postal code 2440 and i only want to use math.pow on the 2 is that possible? if so how?

Answer 1

int pcode = 2440;
int pdigit = pcode/1000; //pdigit = 2

Then do whatever you want with pdigit.

Answer 2

This realization is universal and less magical than Zen's one (will work when code lenght will change).
var code = "2440"; // our postal code
var first = code[0]; // first letter of code
var firstInt = Convert.ToInt32(first); // first letter converted to int
var result = Math.Pow(firstInt, 2); // result

Answer 3

@Ivan G,

that, your answer, is also the first algorithm that came into my mind after reading the problem 😂

Answer 4

int pcode = 2440;

double result = Math.Pow(double.Parse(""+(""+pcode)[0]), exponent);

//that^ gets the first number and raises it to the value you placed to exponent variable.

This is similar to what Ivan G has already posted, I just put them in a single line.

Answer 5

allright, thanks for the answers
