+    Result is the base-2 logarithm of x, i.e., the value y which satisfies the
+    equation x = 2**y. The resulting value is NaN if x < 0. Moreover:
+
+    ```
+    log(Inf) = Inf
+    log(1.0) = +0
+    log(±0) = -Inf
+    ```
+    
+    The operand x must be a scalar or vector whose component type is 16-bit or
+    32-bit floating-point.
+
+    Result Type and the type of x must be the same type. Results are computed
+    per component.
