A more efficient implementation might be something like this: char nthdigit(int x, int n) { while (n–) { x /= 10; } return (x % 10) + ‘0’; } This saves the effort of converting all digits to string format if you only want one of them. And, you don’t have to allocate space for … Read more
This question is actually a very interesting one which mathematicians have devoted a fair bit of thought to. You can read about it in this article, which is a fascinating and accessible read. Briefly, a guy named Tibor Rado set out to find some really big, but still well-defined, numbers by defining a sequence called … Read more
1e5 is a number expressed using scientific notation, specifically E notation, and it means 1 multiplied by 10 to the 5th power (the ‘e’ meaning ‘exponent’). So 1e5 equals 1*100000 and is equal to 100000. The three notations are interchangeable meaning the same.
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
The number_format filter has been included in the Twig core since the end of December 2011. The relevant commit is here. Usage: number_format(decimals, decimalSeparator, thousandSeparator) {{ total|number_format(2) }} {{ total|number_format(0, ‘.’) }} {{ total|number_format(2, ‘.’, ‘,’) }} Read more about it in the docs
A fixed point number has a specific number of bits (or digits) reserved for the integer part (the part to the left of the decimal point) and a specific number of bits reserved for the fractional part (the part to the right of the decimal point). No matter how large or small your number is, … Read more
https://groups.google.com/group/golang-nuts/msg/71c307e4d73024ce?pli=1 The germane part: Since integer types use two’s complement arithmetic, you can infer the min/max constant values for int and uint. For example, const MaxUint = ^uint(0) const MinUint = 0 const MaxInt = int(MaxUint >> 1) const MinInt = -MaxInt – 1 As per @CarelZA’s comment: uint8 : 0 to 255 uint16 : … Read more
