Number

Numeric data types store numeric values. Number objects are created when you assign a value to them. For example:
var1 = 1
var2 = 10

Python supports four different numerical types:

• int (signed integers) : 10, 5464646546
• float (floating point real values) : 3.14546464646
• complex (complex numbers) : 9.322e+26j

Mathematical Functions

• abs(x)
• ceil(x)
• cmp(x, y) : -1 if x < y, 0 if x == y, or 1 if x > y
• exp(x)
• fabs(x) : The absolute value of x.
• floor(x)
• log(x) : The natural logarithm of x, for x> 0
• log10(x) : The base-10 logarithm of x for x> 0
• max(x1, x2,...)
• min(x1, x2,...)
• modf(x) : The fractional and integer parts of x in a two-item tuple.
• pow(x, y) : The value of x**y.
• round(x [,n])
• sqrt(x)

Random Number Functions

Random numbers are used for games, simulations, testing, security, and privacy applications. Python includes following functions that are commonly used.

• choice(seq)
• randrange ([start,] stop [,step])
• random()
• seed([x]) : Sets the integer starting value used in generating random numbers. Call this - function before calling any other random module function. Returns None.
• shuffle(lst)
• uniform(x, y) : A random float r, such that x is less than or equal to r and r is less than y

Trigonometric Functions

• acos(x)
• asin(x)
• atan(x)
• atan2(y, x)
• cos(x)
• hypot(x, y)
• sin(x)
• tan(x)
• degrees(x)
• radians(x)

Mathematical Constants

• pi : The mathematical constant pi
• e : The mathematical constant e
