Conversion overflows Error when decimal is too long Convert a date time in to a 24 hours format from 12 hours format. convert a string to nullable decimal Convert an HTML content to byte array Convert any json string to an array or object in c# convert ASP to HTML Convert Blob to Byte...
The Integer-Overflow-to-Buffer-Overflow (IO2BO) vulnerability has been widely exploited by attackers to cause severe damages to computer systems. Automatically identifying this kind of vulnerability is critical for software security. Despite many works h
Bonus something that you might not have known your cpu when computing a multiplication uint64_t * uint64_t always produces a 128bit output (and you need those to do the multi unit multiplication), it just happens that the way the C++ language is defined it just throws away the high bits...
I want to point out that these functions are being used a great deal in Windows Vista, primarily in code that calculates buffer sizes and array offsets. I wouldn’t use them for all arithmetic, just when you’re calculating an index, buffer size or computing some other form of bound chec...
Small portable arbitrary-precision integer arithmetic library in pure Lua for computing with large integers. Different from most arbitrary-precision integer libraries in pure Lua out there this one uses an array of lua integers as underlying data-type in its implementation instead of using strings or...
enough; in fact, any value above 0x3FFFFFFF (which is still a positive value that passes the check at [2]), once used in the multiplication at [3], will make ssize (declared as a size_t, so either 32 bits or 64 bits wide, depending on the model) overflow and, therefore, wrap....
Pingback:Powers of two « Computing: the Science of Nearly Everything Liorsays: January 25, 2012 at 2:58 pm Another way I was today inform of (assuming word length is reasonable, n): create a Boolean array, sized 2^n. For each element, store true if the index is a power of two...

to as Single Instruction Multiple Data (SIMD) processing. Typically, integer instructions operate on individual integer data elements (A+B). The SIMD instructions, however, operate on integer data arrays (A[1 . . . n]+B[1 . . . n]), where n is the number of elements in the array....
