=

Outputs high logic while two signals are equal within the selected approximate or exact comparison mode.

What it does #

The Equals comparator checks both input samples continuously. Its normal mode allows a small difference so moving signals can still count as equal; Exact requires identical floating-point values.

Controls and ports #

Control	Label	Official description
exact	Exact	Requires the signals to be identical floating-point values, which may prove too stringent when working with two moving signals
table	Truth table	A  B = 0 0 1 0 1 0 1 0 0 1 1 1

Practical uses #

• Detect when a counter, phase-derived value, or control signal reaches a target.
• Create short logic regions where two moving waveforms cross or overlap.
• Use Exact only for values created by the same deterministic logic path or for explicit discrete states.

Things to know #

• Approximate equality is usually more useful for continuously moving signals because exact sample values rarely match.
• Exact mode compares stored floating-point values, not values rounded for display.
• A rapidly changing comparison can produce very narrow pulses at audio rate.

Technical details #

No Nitro implementation has been confirmed for this visible module. The behavior is described conservatively from module metadata and editorial research.

For each sample the output is 1 when the selected equality predicate is true and 0 otherwise. Exact mode is the direct predicate a == b; normal mode applies Bitwig's undocumented near-equality tolerance around a - b = 0. The visible truth table confirms equality for the binary 0/1 cases.

Open questions #

• Measure the approximate-mode tolerance, whether it is absolute or relative, and its behavior for NaN and signed zero.

Version and sources #

Checked against Bitwig Studio 6.0.6. This page combines Bitwig's module metadata, the existing Grid course and guides, and Nitro analysis where the mapping is strong enough to support a technical statement.
