# =============================================================================
# fractus — Primitive floating-point number type
# =============================================================================
#
# What this teaches:
#   • Primitive floating-point number type.
#   • Related keywords: numerus, ↦
#
# Common mistakes:
#   • Using `≡` for direct floating-point equality — float equality is unreliable due to precision; use `.approximata()` for tolerance-based comparison.
#
# See also: numerus, ↦

# fractus comparison and ordering intrinsics
#
# Compiler-owned fractus methodi — absolutum, signum, minimus, maximus.
#
# GRAMMAR:
#   valor.absolutum() | valor.signum()
#   valor.minimus(other) | valor.maximus(other)
#
# Mirrors numerus-methodi.fab for floating-point; Wasm tier Runnable.
#
# EXPECTED OUTPUT:
#   Smoke asserts exit 0 only.
