Py3k's function overloading should fix this:
@overloaded
def sqrt(value):
raise TypeError("Cannot take square root of %s" % type(value).__name__)
@sqrt.overload
def sqrt_float(value : float):
return math.sqrt(value)
@sqrt.overload
def sqrt_complex(value : complex):
return cmath.sqrt(value)
@sqrt.overload
def sqrt_decimal(value : decimal):
return value.sqrt()
# Similar overloads can be added for the types in gmpy and numpy.
Cheers,
Nick.
