This function returns the number of bytes written. Result=String(temp)+result //Add this digit to the left of the string For the Arduino boards with multiple serial ports, the function takes the serial port object as the argument. Here’s the code, which should work for all Arduino-compatible devices: void bigPrint(uint64_t n) //Catch the zero case Returns The first byte of incoming serial data available (or -1 if no data is available) - int. Floats are similarly printed as ASCII digits, defaulting to two decimal places. Numbers are printed using an ASCII character for each digit. It can be done in C readily enough, but the BASIC-like string concatenation capabilities of Arduino C make it easy. See the list of available serial ports for each board on the Serial main page. Prints data to the serial port as human-readable ASCII text. It’s not super efficient, needing an integer division operation for each digit - but it will still run in O(log(n)) time, and shouldn’t take very long at all, even for large numbers. So, to print out large numbers, take the number modulo ten, add that to the left end of your string, take it away from the original number, and divide it by ten. Integers, in any base, can be constructed digit by digit, and Arduinos can still do math with 64-bit numbers. So I came up with a hack: use long division. The printed data is stored in the ASCII (American Standard Code for Information Interchange) format. The proper solution would be to find a way to include 64-bit capable printf() code in the Arduino C compiler - but I suspect that if this were easy, someone would have done it by now. print ( ) in Arduino prints the data to the serial port. Trying an end run using tricks like sprintf(myString,”%llu”,bigValue) doesn’t work, either. to Arduino Developer's List Hi everyone, what do you think of the idea to overload the print and println methods with a format-string as second parameter The format-string would be. (After all, an 8-bit microcontroller has to do a lot of shuffling and carrying to do math with them.) Arduino C’s usual, super easy to use Serial.Print() function doesn’t understand how to handle anything larger than 32 bits. Unfortunately, these large numbers, being newer than their 16-bit and 32-bit counterparts, aren’t always supported as well on smaller devices like microcontrollers. C provides the “unsigned long long int” (or uint64_t) type, which can hold numbers up to 2^64-1, and this covers nearly all of the cases that don’t fit in 32 bits. There’s good support for 64-bit numbers on desktop software, too. It accepts various data types such as integers, floating-point numbers. (It was the memory addressing that made it happen.) print() function is used to send data as human-readable text over the UART interface. 32-bit math has become limiting, which is why computers switched to 64-bit hardware about ten years ago. Am I seeing what it says here: '1 An rvalue of type char, signed char, unsigned char, short int, or unsigned short intcan be converted to an rvalue of type int if int can represent all the values of the source type otherwise, the source rvalue can be converted to an rvalue of type unsigned int. It’s not super efficient, needing an integer division operation for each.

Integers, in any base, can be constructed digit by digit, and Arduinos can still do math with 64-bit numbers. Large as it is, four billion (or more) is increasingly a perfectly reasonable number to be working with. But for now, printing an integer will print its numeric value. 2^32 (4,294,967,296) sounds like a big number.
