Decimal # as _ integer _ ratio():as _ integer _ ratio()是一个 Decimal 类方法，它在移出系数最右边的数字直到只剩下前导数字时返回指数:作为一对(n，d)
语法: Decimal.as_integer_ratio()
参数:十进制值
返回:移出系数最右边的数字直到只剩下前导数字后的指数:成对(n，d)
代码# 1:as _ integer _ ratio()方法示例
# Python Program explaining
# as_integer_ratio() 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.as_integer_ratio() method
print ("\n\nDecimal a with as_integer_ratio() method : ", a.as_integer_ratio())
print ("Decimal b with as_integer_ratio() method : ", b.as_integer_ratio())
输出:
Decimal value a : -1
Decimal value b : 0.142857
Decimal a with as_integer_ratio() method : (-1, 1)
Decimal b with as_integer_ratio() method : (142857, 1000000)
代码# 2:as _ integer _ ratio()方法示例
# Python Program explaining
# as_integer_ratio() 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.as_integer_ratio() method
print ("\n\nDecimal a with as_integer_ratio() method : ", a.as_integer_ratio())
print ("Decimal b with as_integer_ratio() method : ", b.as_integer_ratio())
输出:
Decimal value a : -3.14
Decimal value b : 3.21E+7
Decimal a with as_integer_ratio() method : (-157, 50)
Decimal b with as_integer_ratio() method : (32100000, 1)
