System.Decimal string.format issue

Question

From on December 9, 2014 18:12

When I run the following program, I cannot format a System.Decimal. I have an integration with a .NET library that returns a decimal type that I need to display in the ironpython script.

import System
f = 1.42742
d = System.Decimal(f)
print "{}".format(d)            # 1.42742
print "{:,.2f}".format(f)       # 1.43
print "{:,.2f}".format(d * 1.0) # 1.43
print "{:,.2f}".format(d)       # 12f WRONG

Can you try converting to a decimal.Decimal first? d = decimal.Decimal(System.Decimal(f))

Handling System.Decimal directly is preferable but this might at least give you a workaround.
