Well, sometimes more discussion == less consensus :)

But it's really easy to roll your own:

from decimal import Decimal

def args2dec(fn):
    '''*args to Decimal decorator'''
    float2dec = lambda f: Decimal(str(f))
    def _args2dec(*args):
        args = map(float2dec, args)
        return fn(*args)
    return _args2dec

def drange(start, stop, step):
    while start < stop:
        yield start
        start += step
