P1223Mason Number accepted Tags: NOIP universal group 2003[Display label]DescribeThe prime number of a shape such as 2^p-1 is called Mason, at which point P must also be a prime. But the reverse is not necessarily, that is, if P is a prime

Python-Find the nth Moenissen number __python

Topic Content: Find the nth number of Moenissen. P is prime and M is prime, and satisfies the equation m=2**p-1, then the M is called Moenissen number. For example, p=5,m=2**p-1=31,5 and 31 are primes, so 31 is a Moenissen number. input Format: Enter with the input () funct

Number types for Python

version, integers are also divided into general integers (32-bit) and long integers (infinite precision), with long integers ending in L. With the Python3, there is only one form of integer, with infinite precision. Of course, the integers in Python also have binary (0bxxxxxxxx), octal (0oxxxxxxxx), and hexadecimal (0x xxxxxxxx) forms. Conversion of decimal number to other binary: S=16print (Bin (s)) prin

5 Python Data Type-number

Python random number function Random numbers can be used in mathematics, games, security and other fields, but also often embedded in the algorithm to improve the efficiency of the algorithm and improve the security of the program. Python contains the following common random number

Python Random Number

Python's ability to generate random numbers is implemented in the random module. A pseudo-random number generator with various distributions is implementedThe module can generate 0 to 1 floating-point random numbers, and can be randomly selected in a sequence. The resulting random number can be evenly distributed. Gaussian distribution, logarithmic normal distrib

integer down, such as x=1.2, to return 1 Math.pow (x,y) # exponential operation, get x y-square Math.log (x) # logarithm, the default base is E. You can use the base parameter to change the bases of the logarithm. Like Math.log (100,base=10) MATH.SQRT (x) # square root Trigonometric functions: Math.sin (x), Math.Cos (x), Math.tan (x), Math.asin (x), Math.acos (x), Math.atan (x) These functions receive an X in radians (radian) as an argument.
