LIBRARY
Math.Tests.BooleanToReal
Converts constant and time-varying Boolean signals to Real.
Chains Constant(1.0) → RealToBoolean(threshold=0.5) → BooleanToReal and verifies that a true Boolean input produces realTrue=1.0. A second chain feeds a sine wave (amplitude 1) through RealToBoolean into BooleanToReal so the Boolean toggles and the Real output alternates between its false and true values.
