  Wrong type coercion on input arguments
  If the following snippet, it looks like first calling the function with int arguments then coerces any further float arguments to int:
  
  ```
  >>> @jit(nopython=True)
  ... def mpow(a, b):
  ...     return math.pow(a, b)
  ... 
  >>> 
  >>> mpow(0, 1)
  0.0
  >>> mpow(0, 0.666)
  1.0
  >>> mpow(0, 1.666)
  0.0
  ```
  
  It doesn't happen if the function is called with float arguments first:
  
  ```
  >>> @jit(nopython=True)
  ... def mpow2(a, b):
  ...     return math.pow(a, b)
  ... 
  >>> mpow2(0, 0.666)
  0.0
  >>> mpow2(0, 1)
  0.0
  >>> mpow2(0, 0.666)
  0.0
  ```
