Decimal # canonical():canonical()是一个 Decimal 类方法，返回 Decimal 值的规范编码。
语法:十进制.规范()
参数:十进制值
返回:十进制值的规范编码。
代码#1:规范()方法示例
# Python Program explaining
# canonical() 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.canonical() method
print ("\n\nDecimal a with canonical() method : ", a.canonical())
print ("Decimal b with canonical() method : ", b.canonical())
输出:
Decimal value a : -1
Decimal value b : 0.142857
Decimal a with canonical() method : -1
Decimal b with canonical() method : 0.142857
代码#2:规范()方法示例
# Python Program explaining
# canonical() 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.canonical() method
print ("\n\nDecimal a with canonical() method : ", a.canonical())
print ("Decimal b with canonical() method : ", b.canonical())
输出:
Decimal value a : -3.14
Decimal value b : 3.21E+7
Decimal a with canonical() method : -3.14
Decimal b with canonical() method : 3.21E+7
