**Motivation**
**Notes and Observations**:
* These instructions are present in many other ISAs.
-* JavaScript rounding as one instruction saves 32 scalar instructions
+* ECMAScript rounding as one instruction saves 32 scalar instructions
including seven branch instructions.
* Both sets are orthogonal (no difference except being Single/Double).
This allows IBM to follow the pre-existing precedent of allocating
