👉 Foute in mathematics refers to a number that is not an integer, but instead represents a decimal or fractional part of an integer. This can be particularly useful when dealing with decimals where you want to represent numbers like 1/3 or 2.5 as integers. Foute is also used in the context of complex analysis and mathematical physics, especially in quantum mechanics, where it refers to a quantity that cannot be expressed purely as a real number.
