The omega constant is a mathematical constant defined as the unique real number that satisfies the equation = It is the value of W(1), where W is Lambert's W function. The name is derived from the alternate name for Lambert's W function, the omega function. The numerical value of Ω is given by
The product logarithm Lambert W function plotted in the complex plane from −2 − 2i to 2 + 2i The graph of y = W(x) for real x < 6 and y > −4.The upper branch (blue) with y ≥ −1 is the graph of the function W 0 (principal branch), the lower branch (magenta) with y ≤ −1 is the graph of the function W −1.
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
One of the main applications of this function is in the resolution of the equation z = ln(z), as the only solution is given by z = e −ω(π i).. y = ω(z) is the unique solution, when for x ≤ −1, of the equation y + ln(y) = z.
the time constant of any device, such as an RC circuit; proper time in relativity; one turn: the constant ratio of a circle's circumference to its radius, with value (6.283...).

LibreOffice Calc is the spreadsheet component of the LibreOffice software package. [5] [6]After forking from OpenOffice.org in 2010, LibreOffice Calc underwent a massive re-work of external reference handling to fix many defects in formula calculations involving external references, and to boost data caching performance, especially when referencing large data ranges.
In mathematics, omega function refers to a function using the Greek letter omega, written ω or Ω. Ω {\displaystyle \Omega } (big omega) may refer to: The lower bound in Big O notation , f ∈ Ω ( g ) {\displaystyle f\in \Omega (g)\,\!} , meaning that the function f {\displaystyle f\,\!} dominates g {\displaystyle g\,\!} in some limit
Let k = 1/Ω, that is, the reciprocal of the Omega constant. Then it holds that: = That is, it imitates the power rule of derivatives (even though it's not a polynomial, but an exponential function with base k) in reducing the exponent by 1. The reciprocal Omega constant is the unique exponential base for which this is true.
