0125

0125 is a string of digits that can appear in mathematics, computing, and cataloging as a numeric value or as an identifier. When interpreted as a decimal numeral, 0125 represents the number 125. In contexts where a leading zero signals octal notation, as in some programming languages, 0125 is an octal literal equal to 85 in decimal; the decimal value 125 can be written in octal as 175. In hexadecimal, 125 equals 0x7D, and in binary it equals 1111101.

125 has several mathematical properties. It is the cube of 5 (5^3) and thus a perfect cube. Its prime factorization is 5 cubed, and it is an odd composite number. It also serves as a point of reference for base conversion demonstrations, since its representations across bases are straightforward to compute.

In encoding and notation, numbers with leading zeros often appear in various systems. For example, Unicode code points are commonly written in the form U+0125, where the digits indicate a hexadecimal value. The code point 0125 (hex) corresponds to a specific character in the Unicode standard, illustrating how numeric codes are used to identify symbols in digital text.

In real-world usage, 0125 can function as a model number, catalog or part identifier, file-name component, or a year label (for example, 125 CE). As a simple three-digit sequence, it appears across contexts that require compact numeric labeling. See also: 125 (number), octal numeral system, Unicode.
