Scalar operations on int, float, and bool in function signatures.

# =============================================================================
# scalaria — Scalar operations on int, float, and bool in function
# signatures.
# =============================================================================
#
# What this teaches:
#   • Primitive type operations — demonstrates `int` arithmetic, `float`
#     division, `bool` comparison and boolean logic in function signatures
#   • Function composition — shows how scalar types compose through parameters
#     and return types
#
# Common mistakes:
#   • Mixing `int` and `float` without explicit `↦` conversion — primitive families have distinct type widths (SEM008).
#
# See also: int, float, bool
# =============================================================================



# scalaria — scalar operations on primitive types
#
# Demonstrates int, float, and bool parameters with arithmetic,
# comparison, and boolean logic in function signatures.
#
# GRAMMAR:
#   funcDecl :← 'fn' ident '(' paramList ')' ('→' type)? block
#
# EXPECTED OUTPUT:
#   Compile-only declaration tour (no main).

fn numerica(int a, int b) → int {
    return (a + b) * 2
}

fn fracta(float a, float b) → float {
    return (a + b) / 2.0
}

fn comparata(int a, int b) → bool {
    return a ≤ b
}

fn logica(bool a, bool b) → bool {
    return not a and b
}
