Hilbert smith inner product wiki

In mathematics, an inner product space (or, rarely, a Hausdorff pre-Hilbert space ) is a real vector space or a complex vector space with an operation called an inner product. The inner product of two vectors in the space is a scalar, often denoted with angle brackets such as in .

Completeness is what differentiates the two. Not every metric space can be defined by an inner product, for instance the space of continuous functions on [ 0, 1] with the supremum norm as its metric doesn't come from an inner product.
