# ⌊x⌉ — Rounding glyphs in the Latin surface.

#
# What this teaches:
#   • The same three glyphs in every locale; nearest sends ties to even.
#
# See also: ⌊x⌋, ⌈x⌉

# EXPECTED OUTPUT:
#   2, 3, 2, 4, -2, 2, 3

# =============================================================================
# ⌊x⌉ — Rounding glyphs: floor, ceiling, and nearest with ties to even.
# =============================================================================
#
# What this teaches:
#   • `⌊x⌋` floor, `⌈x⌉` ceiling, `⌊x⌉` nearest.
#   • Nearest sends a tie to the even neighbour: `⌊2.5⌉` is 2, `⌊3.5⌉` is 4.
#
# Common mistakes:
#   • Writing `⌈x⌋` — it is a named error; write `⌊x⌉` for nearest.
