When using the sum filter on an array containing floats, we get a BigDecimal result, which is rendered in scientific notation.

require 'liquid'

template = Liquid::Template.parse("Result: {{ a | sum }}")
puts template.render!({"a" => [0.1, 0.2, 0.3]})

Output

Result: 0.6e0

Expected output

Result: 0.6

For consistency with existing math filters, would it be possible to convert a BigDecimal result to a float, just like the round filter does?

Many thanks.
