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.

The halfactorial symbol made my math problems shorter for my students to solve!
