So, now that we've talked about overflow and underflow, let's talk about efficiency considerations. Python 2 has two integer types: int, which is a signed integer whose size equals your machine's word size (but is always at least 32 bits), and long, which is unlimited in size. To convert it to a float, you just assign that value to a float variable. it is 32-bit or 64-bit. Is it OK to ask the professor I am applying to for a recommendation letter? A signed integer is a 32-bit integer in the range of -(2^31) = -2147483648 to (2^31) 1=2147483647 which contains positive or negative numbers. This is often used in encryption and security keys. It is the same as multiplying x with 2 raised to the power of y(2**y). This will truncate your 64-bit value to a 32-bit value, but note that there is absolutely no way to get the 64-bit value back, this is a destructive method. Diagnosing and fixing this will be both painful and costly. Convert from int to float, you can not do anything 32-bit 64-bit. A data type object (an instance of numpy.dtype class) describes how the bytes in the fixed-size block of memory corresponding to an array item should be interpreted.
