''' Purpose: demonstrate decimal arithmetic 

    Things to remember:
        Arithmetic operations involving decimals ALWAYS produce decimal values!!!
    
        Python represents a decimal number as a float

# PYTHON NUMBER TYPES
    # 3 (int)
    # 3.0 (float / decimal)

# name some values
x = 15.0        # float
y = 6.25          # float

print()

print( 'Values of interest' )

print()

print( 'x =', x )
print( 'y =', y )

print()

reply = input( 'Enter when ready: ' )

# perform amd display some float calculations
total        = x +  y
difference   = x -  y
product      = x *  y
dec_quotient = x /  y
int_quotient = x // y # It will produce the integer result but will be represented as a float since it's float//float
remainder    = x %  y
power        = x ** y

# SNAKE CASE
    # Style rule for variable naming
    # variables will multiple words will have _ (underscores) between the words
    # a_long_variable_name = 2

print( 'x + y  =', total )
print( 'x - y  =', difference )
print( 'x * y  =', product )
print( 'x / y  =', dec_quotient )
print( 'x // y =', int_quotient )
print( 'x % y  =', remainder )
print( 'x ** y =', power )

print()

reply = input( 'Enter when ready: ' )

# IMPORTANT
    # int( x ) -> Takes whatever is in the parentheses and convert it to an integer
    # Chops off decimal portion

int_x = int( x )

print( 'int( x ) =',  int_x )

# int(3.75) -> 3
# int(0.2) -> 0
# int(-3.7) -> -3
