Topological Vector Spaces, II, p. 40, § 5. Separation of convex sets

Let ff be a continuous affine function in XX; then there exists a sequence (hn)(h_n) of elements of LL which converges uniformly to ff in XX.

For, prop. 6 and Dini’s theorem (GT, X, § 4.1, th. 1) show that for all nn there exists hn∈Lh_n \in L such that f≤hn≤f+1/nf \leq h_n \leq f + 1/n.

Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
