代码1：to_integral()方法示例
# Python Program explaining
# to_integral() method
# loading decimal library
from decimal import *
# Initializing a decimal value
a = Decimal(1.898989)
b = Decimal(2.0)
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
# Using Decimal.to_integral() method
print ("\n\nDecimal a with to_integral() method : ", a.to_integral())
print ("Decimal b with to_integral() method : ", b.to_integral())
输出：
Decimal value a : 1.8989890000000000380708797820261679589748382568359375
Decimal value b : 2
Decimal a with to_integral() method : 2
Decimal b with to_integral() method : 2
代码2：to_integral()方法的示例
# Python Program explaining
# to_integral() method
# loading decimal library
from decimal import *
# Initializing a decimal value
a = Decimal(3.14)
b = Decimal(15)
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
# Using Decimal.to_integral() method
print ("\n\nDecimal a with to_integral() method : ", a.to_integral())
print ("Decimal b with to_integral() method : ", b.to_integral())
输出：
Decimal value a : 3.140000000000000124344978758017532527446746826171875
Decimal value b : 15
Decimal a with to_integral() method : 3
Decimal b with to_integral() method : 15
