+    Syntax:

+    ```
+    operation ::= ssa-id `=` `math.fpowi` ssa-use `,` ssa-use `:` type
+    ```
+
+    The `fpowi` operation takes a `base` operand of floating point type
+    (i.e. scalar, tensor or vector) and a `power` operand of integer type
+    (also scalar, tensor or vector) and returns one result of the same type
+    as `base`. The result is `base` raised to the power of `power`.
+    The operation is elementwise for non-scalars, e.g.:
+    ```mlir
+    %v = math.fpowi %base, %power :
+        (vector<2xf32>, vector<2xi32) -> vector<2xf32>
+    ```
+    The result is a vector of:
+    ```
+    [<math.fpowi %base[0], %power[0]>, <math.fpowi %base[1], %power[1]>]
+    ```
+
+    Example:
+
+    ```mlir
+    // Scalar exponentiation.
+    %a = math.fpowi %base, %power : (f64, i32) -> f64
+    ```
+  }];

+  //       point type of the base.
