Python|十进制 compare_total_mag() 方法
Decimal#compare_total_mag() : compare_total_mag()是一个 Decimal 类方法,它通过使用它们的抽象表示而不是它们的值来比较两个 Decimal 值,但忽略每个操作数的符号。
Syntax:
Decimal.compare_total_mag()
Parameter:
Decimal values
Return:
1 - if a > b
-1 - if a < b
0 - if a = b
代码 #1:compare_total_mag() 方法的示例
# Python Program explaining
# compare_total_mag() 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.compare_total_mag() method
print ("\n\nDecimal a with compare_total_mag() method : ", a.compare_total_mag(a))
print ("Decimal a with compare_total_mag() method : ", a.compare_total_mag(b))
print ("Decimal b with compare_total_mag() method : ", b.compare_total_mag(a))
输出 :
Decimal value a : -1
Decimal value b : 0.142857
Decimal a with compare_total_mag() method : 0
Decimal a with compare_total_mag() method : 1
Decimal b with compare_total_mag() method : -1
代码 #2:compare_total_mag() 方法的示例
# Python Program explaining
# compare_total_mag() 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.compare_total_mag() method
print ("\n\nDecimal a with compare_total_mag() method : ", a.compare_total_mag(a))
print ("Decimal a with compare_total_mag() method : ", a.compare_total_mag(b))
print ("Decimal b with compare_total_mag() method : ", b.compare_total_mag(a))
输出 :
Decimal value a : -3.14
Decimal value b : 3.21E+7
Decimal a with compare_total_mag() method : 0
Decimal a with compare_total_mag() method : -1
Decimal b with compare_total_mag() method : 1
