.. _auto_math_offset_scale:

*OFFSET A VALUE THEN SCALE IT *
===============================

Applies a linear offset-then-scale transformation to a scalar value, computing `(value + offset) * scale`. Use this worker whenever a raw scalar needs to be shifted and/or re-scaled before passing it downstream in a workflow.

When to use

     - Description
   * - Data To Be Scaled And Offset
     - datatobescaledandoffset
     - scalar
     - —
     - 
     - The raw scalar value to transform; dimensionless or any unit — the offset and scale must be consistent with this value's units.
   * - Scale
     - scale
     - float
     - 1.0
     - 
     - Multiplicative scale factor applied after the offset; dimensionless float, default 1.0 (no scaling).
   * - Offset
     - offset
     - float
     - 0.0
     - 
     - Additive offset added to the input value before scaling; must share the same units as the input, default 0.0 (no offset).
