Code #1 : Example for next_minus() method

# Python Program explaining
# next_minus() 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_minus() method
print ("\n\nDecimal a with next_minus() method : ", a.next_minus())

print ("Decimal a with next_minus() method : ", a.next_minus())

print ("Decimal b with next_minus() method : ", b.next_minus())

Output :

Decimal value a :  -1
Decimal value b :  0.142857


Decimal a with next_minus() method :  -1.000000000000000000000000001
Decimal a with next_minus() method :  -1.000000000000000000000000001
