You can still use the Java conversion by calling the static function on java.lang.Integer: val hexString = java.lang.Integer.toHexString(i) And, starting with Kotlin 1.1, there is a function in the Kotlin standard library that does the conversion, too: fun Int.toString(radix: Int): String Returns a string representation of this Int value in the specified radix. Note, however, … Read more
C++11 introduced user defined literals. It can be used like this: inline constexpr unsigned char operator “” _uchar( unsigned long long arg ) noexcept { return static_cast< unsigned char >( arg ); } unsigned char answer() { return 42; } int main() { std::cout << std::min( 42, answer() ); // Compile time error! std::cout << … Read more
How about this? >>> s=”23.45678″ >>> int(float(s)) 23 Or… >>> int(Decimal(s)) 23 Or… >>> int(s.split(‘.’)[0]) 23 I doubt it’s going to get much simpler than that, I’m afraid. Just accept it and move on.
When writing in C or C++, every datatype is architecture and compiler specific. On one system int is 32, but you can find ones where it is 16 or 64; it’s not defined, so it’s up to compiler. As for long and int, it comes from times, where standard integer was 16bit, where long was … Read more
Note: There is now math.isqrt in stdlib, available since Python 3.8. Newton’s method works perfectly well on integers: def isqrt(n): x = n y = (x + 1) // 2 while y < x: x = y y = (x + n // x) // 2 return x This returns the largest integer x for … Read more
This version does not suffer from the bug in the previous answers where 999,999 gives you 1000.0K. It also only allows 3 significant figures and eliminates trailing 0’s. def human_format(num): num = float(‘{:.3g}’.format(num)) magnitude = 0 while abs(num) >= 1000: magnitude += 1 num /= 1000.0 return ‘{}{}’.format(‘{:f}’.format(num).rstrip(‘0’).rstrip(‘.’), [”, ‘K’, ‘M’, ‘B’, ‘T’][magnitude]) The output … Read more
The immediate problem is due to you using <= temp.length() instead of < temp.length(). However, you can achieve this a lot more simply. Even if you use the string approach, you can use: String temp = Integer.toString(guess); int[] newGuess = new int[temp.length()]; for (int i = 0; i < temp.length(); i++) { newGuess[i] = temp.charAt(i) … Read more
What’s wrong with return ((x<0) == (y<0)); ?
>>> import re >>> string1 = “498results should get” >>> int(re.search(r’\d+’, string1).group()) 498 If there are multiple integers in the string: >>> map(int, re.findall(r’\d+’, string1)) [498]
Direct from Django model field reference: Field.null If True, Django will store empty values as NULL in the database. Default is False. Note that empty string values will always get stored as empty strings, not as NULL. Only use null=True for non-string fields such as integers, booleans and dates. For both types of fields, you … Read more
