14j

14j is a numeric literal used in some programming languages to denote a purely imaginary number. In mathematics and engineering, the symbol j is commonly used as the imaginary unit, equal to the square root of minus one, so 14j represents 14 times the imaginary unit, i.e., 0 + 14i (or 14j, depending on convention). In programming, 14j appears as a literal representing the complex number with real part zero and imaginary part fourteen.

In Python, 14j is a complex number literal. Its value is 0+14j, and its type is complex. Arithmetic examples include 14j + 2j = 16j, and 14j * 1j = -14. The real and imaginary parts can be accessed as 14j.real (0.0) and 14j.imag (14.0). The built-in str(14j) yields '14j', and complex numbers can also be created using complex(0, 14).

Limitations and usage notes: Not all programming languages support a trailing j suffix for imaginary literals; Python is among the most widely known that do. In broader mathematics and signal processing contexts, j is used interchangeably with i to denote the imaginary unit, with notation differing by field or convention.
