Parameter:
Decimal values
Return:
1 - if a > b
-1 - if a < b
0 - if a = b
代码# 1:compare _ total()方法示例
# Python Program explaining
# compare_total() 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_total() method
print ("\n\nDecimal a with compare_total() method : ", a.compare_total(a))
print ("Decimal a with compare_total() method : ", a.compare_total(b))
print ("Decimal b with compare_total() method : ", b.compare_total(a))
输出:
Decimal value a : -1
Decimal value b : 0.142857
Decimal a with compare_total() method : 0
Decimal a with compare_total() method : -1
Decimal b with compare_total() method : 1
代码# 2:compare _ total()方法示例
# Python Program explaining
# compare_total() 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_total() method
print ("\n\nDecimal a with compare_total() method : ", a.compare_total(a))
print ("Decimal a with compare_total() method : ", a.compare_total(b))
print ("Decimal b with compare_total() method : ", b.compare_total(a))
输出:
Decimal value a : -3.14
Decimal value b : 3.21E+7
Decimal a with compare_total() method : 0
Decimal a with compare_total() method : -1
Decimal b with compare_total() method : 1
