We can convert a signed int to an "unsigned" long as such: public static final int BITS_PER_BYTE = 8; public static long getUnsignedInt(int x) { ByteBuffer buf = ByteBuffer.allocate(Long.SIZE / BITS_PER_BYTE); buf.putInt(Integer.SIZE / BITS_PER_BYTE, x); return buf.getLong(0);...
int n = -1; Write( Convert.ToUInt64(n) ); // Error - Value was either too large or too small for a UInt64 But it works for `Int64`. What's the correct w
to convert an unsigned number to signed number without causing overflow. The stored integer bits of the number will be reinterpreted.
#include <stdlib.h> unsigned long int strtoul(const char * __restrict__ string1, char ** __restrict__ string2, int base);General Description The strtoul() function converts string1, a character string, to an unsigned long int value. The function decomposes the entire string into three ...
1.Convert.ToInt是数据类型转换成int类型 2. 有三种方法toint16,toint32,toint64 int16-数值范围:-32768 到 32767 int32-数值范围:-2,147,483,648 到 2,147,483,647 int64-数值范围:-9223372036854775808 到 9223372036854775808 3.所以,按需使用吧
int sourceNumber = Int32.MinValue; bool isSigned = Math.Sign((int)sourceNumber.GetType().GetField("MinValue").GetValue(null)) == -1; string value = Convert.ToString(sourceNumber, 16); UInt32 targetNumber; try { targetNumber = Convert.ToUInt32(value, 16); if (isSigned && ((target...
