long parseLong(String s) 功能同long parseLong(String s, int radix) ,只是传了个默认进制10,这是Long类中的核心方法,摘一下其中的核心代码,算法也很简单,定义个值为0的long值,通过循环乘进制再加字符串对应位置int值的方式最终得到结果。 longresult=0;inti=0,len=s.length();while(i<len){// Accumulat...
Casting an Int16 varible to Int in C# produces a runtime "Specified cast is not valid" exception casting from object to System.Reflection.PropertyInfo Casting to nullable generics Casting using (decimal) or Convert.ToDecimal ? What to use? Catch an exception from one thread and throw to main...
"%ull" will get interpreted as the format specfier "%u" and an ordinary string of "ll". Passing an long long to be formatted as an unsigned int("%u") will likely give you unpredictable results. You need to use printf("%lld\n", val1); If you had an unsigned long long, you'...

long double:The size of these datatypes is 10 bytes. The format specifier is used for unsigned long double is %Lf. The argument for printf() function that formats a long variabledepends on the datatypes which you're referring to likelong int,long long int, orlong double. There is a diff...
int mag = Long.SIZE - Long.numberOfLeadingZeros(val); int chars = Math.max(((mag + (shift - 1)) / shift), 1); char[] buf = new char[chars]; formatUnsignedLong(val, shift, buf, 0, chars); return new String(buf, true
public static String toString(long i, int radix)Returns a string representation of the first argument in the radix specified by the second argument. If the radix is smaller than Character.MIN_RADIX or larger than Character.MAX_RADIX, then the radix 10 is used instead. If the first ...

HexFormat parseUnsignedLong(String, int) toUnsignedString(long, int)toOctalString public static String toOctalString(long i) Returns a string representation of the long argument as an unsigned integer in base 8. The unsigned long value is the argument plus 264 if the argument is negative; ot...
public int hashCode() {return Long.hashCode(value);}public static int hashCode(long value) {return (int)(value ^ (value >>> 32));}123456 1. 首先将long型值无符号右移32位,再和原来的值进行异或运算,最后返回int类型值。Long类型的数值范围比int类型的大多了,将Long类型的hash值用int表示可想而...
