Decimal#quantize() : quantize() is a Decimal class method which returns a value equal to first decimal value (rounded) having the exponent of second decimal value.
Syntax: Decimal.quantize()
Parameter: Decimal values
Return: a value equal to first decimal value (rounded) having the exponent of second decimal value.
Code #1 : Example for quantize() method
# Python Program explaining # quantize() 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.quantize() method print ("\n\nDecimal a with quantize() method : ", a.quantize(b))   print ("Decimal b with quantize() method : ", b.quantize(b)) |
Output :
Decimal value a : -1 Decimal value b : 0.142857 Decimal a with quantize() method : -1.000000 Decimal b with quantize() method : 0.142857
Code #2 : Example for quantize() method
# Python Program explaining # quantize() 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.quantize() method print ("\n\nDecimal a with quantize() method : ", a.quantize(b))   print ("Decimal b with quantize() method : ", b.quantize(b)) |
Output :
Decimal value a : -3.14 Decimal value b : 3.21E+7 Decimal a with quantize() method : -0E+5 Decimal b with quantize() method : 3.21E+7
