1023 (number)
1023 is the natural number following 1022 and preceding 1024.
Mathematics
1023 is a number whose sum of digits is 6, and is a sum of 5 consecutive primes.It is a sub-perfect power specifically 45 - 1 and 210 - 1. The latter of these makes it a Mersenne number, and both of these cause it to be palindromic when converted to bases 2 and 4.
It is a Stirling number of the second kind, specifically.
There are 1023 polycubes with 7 cells.

Computing
s in computers often run a IEEE 754 64-bit, floating-point excess-1023 format in 11-bit binary. In this format, also called binary64, the exponent of a floating-point number appears as an unsigned binary integer from 0 to 2047, where subtracting 1023 from it gives the actual signed value.1023 is the number of dimensions or length of messages of an error-correcting Reed-Muller code made of 64 block codes.
Technology
The Global Positioning System works on a ten-digit binary counter that runs for 1023 weeks, at which point an integer overflow causes its internal value to roll over to zero again.1023 being, is the maximum number that a 10-bit ADC converter can return when measuring the highest voltage in range.
