# All these are objects, so we can create a new integer, float, or complex number by using the class name and parentheses, which will call its constructor..

### Integers are whole numbers, they do not contain any decimals.
a = 12            # 12
b = -543          # -543
c = +92381201     # 92381201
d = int(3)        # 3
e = int(6.1235)   # 6
f = int(6.98994)  # 6
g = int("512")    # 512
h = int("-8")     # -8

### Floats are integers that allow decimal places. 
i = 3.0
j = 0.1235
k = +987546.56
l = float(105)
m = float(-12.123)
n = float("56")
o = float("63.2")
p = float("inf") # positive infinity
q = float("-inf") # negative infinity
r = float("nan") # not a number
s = 3e12
t = -87E4
u = 2e-20

### Complex numbers, have a real and an imaginary part
v = 8 + 23j
w = -9.21 + 4J
x = 200j
y = complex(23)
z = 23 + 0j
