代码 #1:to_eng_string() 方法的示例
# Python Program explaining
# to_eng_string() method
# loading decimal library
from decimal import *
# Initializing a decimal value
a = Decimal(1.898989)
b = Decimal(2.0)
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
# Using Decimal.to_eng_string() method
print ("\n\nDecimal a with to_eng_string() method : ", a.to_eng_string())
print ("Decimal b with to_eng_string() method : ", b.to_eng_string())
输出 :
Decimal value a : 1.8989890000000000380708797820261679589748382568359375
Decimal value b : 2
