Dividing by dynamic value doesn't work

[bdobry]

Describe the bug

{%= one / two %}

raises an exception

Error rendering template!
java.lang.ArithmeticException: Non-terminating decimal expansion; no exact representable decimal result.
- java.lang.ArithmeticException Non-terminating decimal expansion; no exact representable decimal result.

for the payload

{
  "one": 4.3,
  "two": 3.0
}

It seems like like the partition part of division is causing the problem here. {%= one / 2 %} works fine but it breaks other way around.

Environment where template is rendered:

• Stencil version: 0.4.1
• Operating System version: Linux Alpine

Thanks for reporting! The bug was that the custom JSON deserializer read BigDecimal values without precision and division would have resulted in a non-terminating decimal expansion. The solution is to limit the division precision to a finite number of digits. (8 in this case.)

Fixed in version 0.4.2 just released.
