0x1D45

0x1D45 is a hexadecimal numeric literal consisting of digits 1, D, 4, 5 with the 0x prefix. In decimal, it equals 7493. The 0x prefix denotes hexadecimal notation and is widely used in programming languages such as C, C++, Java, JavaScript, Python, and many assembly languages, to denote that the number is base-16.

Common uses of hexadecimal literals include representing memory addresses, bitmasks, flags, and numeric constants that map to hardware registers. They also appear in color value representations and various encoding schemes, or as identifiers in binary protocols. Because hexadecimal aligns neatly with binary bit patterns, it is a convenient shorthand for low-level programming tasks.

In Unicode code points, a hexadecimal form such as U+01D45 would denote a specific character; the Unicode standard uses code points in hex form prefixed with U+. The exact character depends on the current Unicode repertoire and standard mappings, and is separate from the numeric value used in programming.

Overall, 0x1D45 serves as a compact example of hex notation commonly encountered in software development, systems programming, and digital encoding contexts. For further reference, see hexadecimal numeral systems, memory addressing, and Unicode code points.
