+    The `nvvm.fadd` operation performs floating point addition of two operands.
+
+    The rounding mode to be used is specified by the `rnd` attribute, 
+    saturation mode by the `sat` attribute, and FTZ by the `ftz` unit attribute.
+    
+    The result type must be at least as wide as the operands. The operands are

```suggestion
When the type of the `result` is wider than the type of the operands, the operands are first converted to the `result` type, and then the addition is performed.
