代码 #1:copy_abs() 方法的示例
# Python Program explaining
# copy_abs() 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.copy_abs() method
print ("\n\nDecimal a with copy_abs() method : ", a.copy_abs())
print ("Decimal b with copy_abs() method : ", b.copy_abs())
输出 :
Decimal value a : -1
Decimal value b : 0.142857
Decimal a with copy_abs() method : 1
Decimal b with copy_abs() method : 0.142857
代码 #2:copy_abs() 方法的示例
# Python Program explaining
# copy_abs() 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.copy_abs() method
print ("\n\nDecimal a with copy_abs() method : ", a.copy_abs())
print ("Decimal b with copy_abs() method : ", b.copy_abs())
输出 :
Decimal value a : -3.14
Decimal value b : 3.21E+7
Decimal a with copy_abs() method : 3.14
Decimal b with copy_abs() method : 3.21E+7
