Vector Arithmetic Subtraction (SUB)

Summary

Element-wise subtraction of two input series.

Formula

outReal[i] = inReal0[i] - inReal1[i]

Inputs

• inReal0 — Minuend series
• inReal1 — Subtrahend series

Outputs

• outReal — Per-element difference inReal0 - inReal1

Properties

Numerical Stability: Start-Independent

☐ Overlap Input
✅ Independent Y-Axis i
☐ Candlestick
☐ Can Output NaN or ±Inf
☐ Identity at Period 1
