It depends on what the integer is supposed to encode. You could convert the date to a number of milliseconds from some previous time. People often do this affixed to 12:00 am January 1 1970, or 1900, etc., and measure time as an integer number of milliseconds from that point. The datetime module (or others … Read more
Here’s a blog post describing the creation of an IsInteger UDF. Basically, it recommends adding ‘.e0’ to the value and using IsNumeric. In this way, anything that already had a decimal point now has two decimal points, causing IsNumeric to be false, and anything already expressed in scientific notation is invalidated by the e0.
Sort your data with: function sortScripts($a, $b) { return $a[‘order’] – $b[‘order’]; } Use $b-$a if you want the reversed order. If the numbers in question exceed PHP’s integer range, return ($a < $b) ? -1 : (($a > $b) ? 1 : 0) is more robust.
The read method returns a sequence of bytes as a string. To convert from a string byte-sequence to binary data, use the built-in struct module: http://docs.python.org/library/struct.html. import struct print(struct.unpack(‘i’, fin.read(4))) Note that unpack always returns a tuple, so struct.unpack(‘i’, fin.read(4))[0] gives the integer value that you are after. You should probably use the format string … Read more
http://dev.mysql.com/doc/refman/5.0/en/integer-types.html The integer overflow will set the max allowed number in the DB as 2147483647 So you need bigint datatype for storing bigger integer
x = [2, 4, 7, 12, 3] sum_of_all_numbers= sum(x) or you can try this: x = [2, 4, 7, 12, 3] sum_of_all_numbers= reduce(lambda q,p: p+q, x) Reduce is a way to perform a function cumulatively on every element of a list. It can perform any function, so if you define your own modulus function, it … Read more
Most processors include a carry flag and an overflow flag to support operations on multi-word integers. The carry flag is used for unsigned math, and the overflow flag for signed math. For example, on an x86 you could add two unsigned 64-bit numbers (which we’ll assume are in EDX:EAX and EBX:ECX) something like this: add … Read more
To find the minimum value of a list, you might just as well use min: x = min(float(s) for s in l) # min of a generator Or, if you want the result as a string, rather than a float, use a key function: x = min(l, key=float)
From this reference: An int was originally intended to be the “natural” word size of the processor. Many modern processors can handle different word sizes with equal ease. Also, this bit: On many (but not all) C and C++ implementations, a long is larger than an int. Today’s most popular desktop platforms, such as Windows … Read more
Math.addExact throws exception on overflow Since Java 8 there is a set of methods in the Math class: toIntExact(long) addExact(int,int) subtractExact(int,int) multiplyExact(int,int) …and versions for long as well. Each of these methods throws ArithmeticException if overflow happens. Otherwise they return the proper result if it fits within the range. Example of addition: int x = … Read more
