frange

Data type for efficiently storing large arrays of equally separated data in python, similar to range but for floats.

This is a simple package containing a class which can be used in a similar manner to the built-in range function in python. It can be used to create a generator or a numpy array containing the desired, equally seperated, values.

It generates numbers in the same manner as numpy's arange function.

Example usage

# you can create an frange object like so
>>> time = frange(0, 2, 1e-3)

# you can print the length of the array it will generate
>>> printlen(time) # prints length of frange, just like an array or list

# you can create a generator
>>> generator = time.get_generator() # gets a generator instance
>>> for i in generator: # iterates through printing each element
>>>     print(i)

# you can create a numpy array
>>> array = time.get_array() # gets an array instance
>>> newarray = 5 * array # multiplies array by 5

# you can also get the start, stop and step by accessing the slice parameters
>>> start = time.slice.start
>>> stop = time.slice.stop
>>> step = time.slice.step
