Firstly, there could be two values that you’re referring to: Underlying Value If you are asking about the underlying value, which could be any of these types: byte, sbyte, short, ushort, int, uint, long or ulong Then you can simply cast it to it’s underlying type. Assuming it’s an int, you can do it like … Read more
In String type we have several method valueOf static String valueOf(boolean b) static String valueOf(char c) static String valueOf(char[] data) static String valueOf(char[] data, int offset, int count) static String valueOf(double d) static String valueOf(float f) static String valueOf(int i) static String valueOf(long l) static String valueOf(Object obj) As we can see those method are … Read more
You can use sprintf to do it, or maybe snprintf if you have it: char str[ENOUGH]; sprintf(str, “%d”, 42); Where the number of characters (plus terminating char) in the str can be calculated using: (int)((ceil(log10(num))+1)*sizeof(char))
Given: xs = [‘1’, ‘2’, ‘3’] Use map then list to obtain a list of integers: list(map(int, xs)) In Python 2, list was unnecessary since map returned a list: map(int, xs)
C++11 introduces std::stoi (and variants for each numeric type) and std::to_string, the counterparts of the C atoi and itoa but expressed in term of std::string. #include <string> std::string s = std::to_string(42); is therefore the shortest way I can think of. You can even omit naming the type, using the auto keyword: auto s = std::to_string(42); … Read more
If you are looking for Uniformly distributed pseudorandom integers use: randi([13, 20])
int is a “most efficient type” in speed/size – but that is not specified by per the C spec. It must be 16 or more bits. int_fast16_t is most efficient type in speed with at least the range of a 16 bit int. Example: A given platform may have decided that int should be 32-bit … Read more
tl;dr: As the reference manual states: A block is a piece of Python program text that is executed as a unit. The following are blocks: a module, a function body, and a class definition. Each command typed interactively is a block. This is why, in the case of a function, you have a single code … Read more
num will always contain an integer because it’s an int. The real problem with your code is that you don’t check the scanf return value. scanf returns the number of successfully read items, so in this case it must return 1 for valid values. If not, an invalid integer value was entered and the num … Read more
Numpy has a hierarchy of dtypes similar to a class hierarchy (the scalar types actually have a bona fide class hierarchy that mirrors the dtype hierarchy). You can use np.issubdtype(some_dtype, np.integer) to test if a dtype is an integer dtype. Note that like most dtype-consuming functions, np.issubdtype() will convert its arguments to dtypes, so anything … Read more
