How do the floor and ceiling functions work on negative numbers?

The integral part or integer part of a number (partie entière in the original) was first defined in 1798 by Adrien-Marie Legendre in his proof of the Legendre's formula. Carl Friedrich Gauss introduced the square bracket notation [x] in his third proof of quadratic reciprocity (1808). This remained the standard in mathematics until Kenneth E.

The preimage always exists, and is defined to be the set of those points that map into T, i.e. f − 1 ( T) = { x ∣ f ( x) ∈ T }. If f has an inverse, there is also the image of T under f − 1 which is. f − 1 () { f − 1 ( y) ∣ y ∈ }. phil norby milwaukee
