## How do you get the first number from an integer?

firstDigit = number/((int)(pow(10,(int)log(number)))); This should get your first digit using math instead of strings. int number = 534; int firstDigit = number/100; ( / ) operator in java divide the numbers without considering the reminder so when we divide 534 by 100 , it gives us (5) .

## How do you find the units digit of a number?

Units digit of Large Numbers – number raised to powerIdentify the units digit in the base ‘x’ and call it say ‘l’. {For example, If x = 24, then the units digit in 24 is 4. Hence l = 4.}Divide the exponent ‘y’ by 4. If the exponent y is exactly divisible by 4. i.e, y leaves a remainder 0 when divided by 4. Then,

## How do you find the nth digit of a number?

Approach: The idea is to skip (N-1) digits of the given number in base B by dividing the number with B, (N – 1) times and then return the modulo of the current number by the B to get the Nth digit from the right.

## How do you find the second digit of a number?

3 Answers. You can do it by dividing by ten and then taking the remainder of division by ten: int second = (number / 10) % 10; In general, you could think of integer-dividing by a k -th power of ten as of dropping k least significant digits.

## How do you get the first digit of a number in Python?

## How do you find the first and last digit of a number?

To find last digit of a number, we use modulo operator %. When modulo divided by 10 returns its last digit. To finding first digit of a number is little expensive than last digit. To find first digit of a number we divide the given number by 10 until number is greater than 10.
