Decimal # next _ 朝向():next _ 朝向()是一个 Decimal 类方法，它返回在朝向第二个小数值的方向上最接近第一个小数值的数字。
语法:decimal . next _ 朝()
参数:十进制值
返回:向第二个小数值方向最接近第一个小数值的数字。
代码# 1:next _ 朝向()方法示例
# Python Program explaining
# next_toward() 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.next_toward() method
print ("\n\nDecimal a with next_toward() method : ", a.next_toward(b))
print ("Decimal b with next_toward() method : ", b.next_toward(b))
输出:
Decimal value a : -1
Decimal value b : 0.142857
Decimal a with next_toward() method : -0.9999999999999999999999999999
Decimal b with next_toward() method : 0.142857
代码# 2:next _ 朝向()方法示例
# Python Program explaining
# next_toward() 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.next_toward() method
print ("\n\nDecimal a with next_toward() method : ", a.next_toward(b))
print ("Decimal b with next_toward() method : ", b.next_toward(b))
输出:
Decimal value a : -3.14
Decimal value b : 3.21E+7
Decimal a with next_toward() method : -3.139999999999999999999999999
Decimal b with next_toward() method : 3.21E+7
