0x73

0x73 is a hexadecimal numeric literal. The prefix 0x indicates base-16. The digits 7 and 3 yield the value 0x73, which is 115 in decimal.

In ASCII and Unicode, 0x73 corresponds to the lowercase letter 's' (Unicode code point U+0073). As such, 0x73 frequently appears in text data and in percent-encoding of URLs where %73 stands for 's'.

In programming, 0x73 can appear as a byte value in data streams, as part of a larger hexadecimal constant, or as an integer literal in source code. For example, 0x73 equals 115 decimal, so a color channel value or opcode that uses 8-bit bytes may contain 0x73 as part of its data.

In URLs, percent-encoding uses two-digit hex codes; therefore %73 encodes the letter 's'. This makes 0x73 a common reference point when discussing how text characters are represented in hexadecimal form across computing and data encoding.
