A separatrix is a symbol or character used to separate different parts of a number or data string. Commonly, it refers to the decimal mark (either a period or a comma) that separates the integer part from the fractional part of a number. It's like a wall 🧱 dividing two sections. The choice between comma and period depends on the country and convention. Other separatrixes include commas or spaces in large numbers. They help prevent confusion.
