Best Answer

It is (2 ^ 64) - 1.

Or UNSIGNED BIGINT Maximum value (databases)

2^64-1=18,446,744,073,709,551,615

it is the answer to the 'chessboard problem' using wheat or rice, dependent on what culture you believe the Chess board originated from, It also shows a quick view of exponential growth.

What are the difference between signed and unsigned data types?

A signed integer represents both positive and negative values, while an unsigned integer represents only positive values. Range depends on the number of bits the compiler assigns for the representation. bits max-negative max-positive max-unsigned 8 -128 +128 255 16 -32768 +32767 65535 32 -2147483648 +2147483647 4294967295 64 -9223372036854775808 +9223372036854775807 18446744073709551615


How do you compute the binary equivalent of a number using a recursive function using C or C plus plus?

Recursion is not the best way of dealing with this. An iterative function would be more efficient. However, the following recursive method will get the job done, if somewhat slowly and painfully (the equivalent iterative method is also shown, with performance timings for comparison): #include <Windows.h> #include <iostream> typedef unsigned long long UINT64; char * Dec2BinRecur( UINT64 Dec, char *Bin, size_t Length ) { if( Length ) { Bin[--Length] = Dec & 1 ? '1' : '0'; Dec2BinRecur( Dec >> 1, Bin, Length ); } return( Bin ); } char * Dec2BinIter( UINT64 Dec, char *Bin, size_t Length ) { while( Length ) { Bin[--Length] = Dec & 1 ? '1' : '0'; Dec >>= 1; } return( Bin ); } int main() { char strFormat[] = "Dec2Bin %I64u %s: %.2f microseconds Answer: %s\n"; LARGE_INTEGER Freq, Start, Finish; QueryPerformanceFrequency( &Freq ); double Recur, Iter; char Bin[65]; memset( Bin, 0, 65 ); memset( Bin, '0', 64 ); UINT64 Dec = 18446744073709551615; QueryPerformanceCounter( &Start ); Dec2BinRecur( Dec, Bin, 64 ); QueryPerformanceCounter( &Finish ); Recur = ( double ) ( Finish.QuadPart - Start.QuadPart ) / Freq.QuadPart; printf( strFormat, Dec, "Recursive", Recur * 1000000, Bin ); QueryPerformanceCounter( &Start ); Dec2BinIter( Dec, Bin, 64 ); QueryPerformanceCounter( &Finish ); Iter = ( double ) ( Finish.QuadPart - Start.QuadPart ) / Freq.QuadPart; printf( strFormat, Dec, "Iterative", Iter * 1000000, Bin ); return( 0 ); } Output: Dec2Bin 18446744073709551615 Recursive: 9.84 microseconds Answer: 1111111111111111111111111111111111111111111111111111111111111111 Dec2Bin 18446744073709551615 Iterative: 1.72 microseconds Answer: 1111111111111111111111111111111111111111111111111111111111111111


If you put one quarter on a single square of a chess board and double it for each square how much money would you get on the last square?

In the last square you will have 2^63 quarters, or 9223372036854775808 quarters ( 2305 843 009 213 693 952 dollars). If you want to add all the quarters of the board, to see how much money you end up with, then you will have: (2^64) - 1 quarters or: 18446744073709551615 quarters. Translated into dollars: 4611 686 018 427 387 903 dollars and three more quarters. I know how many coins there would be 84,432,400,722,241,872 (84 quadrillion 432 trillion 400 billion 722 million 241 thousand 8 hundred 72


What are the rules fr multiplication and divisions of integers?

(positive number) x (positive number) = positive number (positive number)/(positive number) = positive number (positive number) x ( negative number) = negative number (positive number)/( negative number) = negative number (negative number) x (negative number) = positive number (negative number)/(negative number) = positive number


What is the formula for the atomic number?

atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons

How do you find the number of neutrons from the mass number?

To find the number of neutrons from the mass number, subtract the atomic number from the mass number. The atomic number represents the number of protons in an atom, and by subtracting it from the mass number, you can determine the number of neutrons present.
