What is the syntax of isclose() and how to use it ?
And what is the difference between astype() and dtype() ?
There is documentation for all these functions. In the case of isclose, it is a numpy function so try googling “numpy isclose” and it’s also worth a look at “numpy allclose”.
The astype and dtype “methods” are attributes of the “numpy array” class.
Basically dtype gives you the data type of an array object. The elements of a numpy array can have many different possible types.
Here’s a place to start for dtype.
Then the astype() method can be used to force the datatype of an array to a particular data type that you need. That operation is also referred to as “casting” the array. As in “we need to cast the array to 32 bit floats”.
