代碼1：compare()方法示例

# Python Program explaining

# compare() method

# loading decimal library

from decimal import *

# Initializing a decimal value

a = Decimal(-1)

b = Decimal('0.142857')

# printing Decimal values

print ("Decimal value a : ", a)

print ("Decimal value b : ", b)

# Using Decimal.compare() method

print ("\n\nDecimal a with compare() method : ", a.compare(a))

print ("Decimal a with compare() method : ", a.compare(b))

print ("Decimal b with compare() method : ", b.compare(a))

輸出：

Decimal value a : -1

Decimal value b : 0.142857

Decimal a with compare() method : 0

Decimal a with compare() method : -1

Decimal b with compare() method : 1

代碼2：compare()方法的示例

# Python Program explaining

# compare() method

# loading decimal library

from decimal import *

# Initializing a decimal value

a = Decimal('-3.14')

b = Decimal('321e + 5')

# printing Decimal values

print ("Decimal value a : ", a)

print ("Decimal value b : ", b)

# Using Decimal.compare() method

print ("\n\nDecimal a with compare() method : ", a.compare(a))

print ("Decimal a with compare() method : ", a.compare(b))

print ("Decimal b with compare() method : ", b.compare(a))

輸出：

Decimal value a : -3.14

Decimal value b : 3.21E+7

Decimal a with compare() method : 0

Decimal a with compare() method : -1

Decimal b with compare() method : 1
