halfactorial
The Half-Factorial sign, Halfactorial, or just n! . The Half Factorial is an arithmetic operation represented by the custom glyph (the intersecting slashed exclamation mark). It calculates the product of a decreasing sequence of numbers where each subsequent factor drops by exactly 0.5.
Unlike a traditional factorial (n!) which always multiplies all the way down to 1, the Half-Step Factorial terminates after n steps. This prevents the sequence from ever hitting zero or negative numbers, allowing the final output to scale up incredibly fast.
