php get first digit of number

A simple solution is to compute factorial of number, then find first digit in it. Go to the editor Input: Each test case consists of two non-negative integers x and y which are separated by a space in a line. 48. now we will take an short overview of log10() function. The 2 digit representation of current month without leading zero is: 6. If you have a string, you can treat it just like an array to get its first character: $s = '123'; $a = $s[0]; echo $a; // 1 So, you can just use the square brackets. This HTML code creates the text field in which a user enters characters. The above solution causes overflow soon. Add the remainder to a variable. Program to illustrate the working of our solution, int number = 1234; get the digits() { int[4] digits; digits[0] = the first digit of [int number]. After you have your Fingerprint Registration Number, you must register with the Missouri Automated Criminal History Site (MACHS) so that your Criminal History Check can be performed by IdentoGO (the fingerprint services vendor for the state of Missouri). PHP 5.2.2 - 5.2.6 - If start has the position of a negative truncation, FALSE is returned. You can have it automatically deduce the base of the number from the prefix of the string using the same syntax as integer literals in PHP ("0x" for hexadecimal, "0" for octal, non-"0" for decimal) by passing a base of 0 to intval(): 0) { print( number % 10); number = number / 10; } The mod operator will give you the remainder of doing int division on a number. $firstChar = mb_substr ($string, 0, 1, "UTF-8"); //Print out the first character. To, solve this problem, we will extract the first and last digit to number n. And the print their sum. However, if You should have a number variable, you can not use the square brackets. 0 = x, y = 1,000,000 Output: Digit number of sum of two given integers: 2 Click me to see the solution. Method 4: Using CreateFromFormat() method to get month from any date. For example, first digit of x * y is same as x * y * 100 for x > 0 and y > 0. The first place is the 0, the second the 1 and so on. There are many ways to pad leading zeros in string format.
