This is an awful way to test whether a number is shown on the screen:
Then I should see "5"
It is awful because the step above is green for 5, 5123 and -51.
This step definition below makes sure this doesn't happen. You can use it like this:
Then I should see the number 5
The step also works if you you'd like to test that the number is followed by a unit:
Then I should see the amount 5 €
The separator between the number and its unit is allowed to be either a space or a nbsp.
The step definitions require the htmlentities gem.

Then /^I should( not)? see the (?:number|amount) ([\-\d,\.]+)(?: (.*?))?$/ do |negate, amount, unit|
no_minus = amount.starts_with?('-') ? '' : '[^\\-]'
nbsp = 0xC2.chr + 0xA0.chr
regexp = Regexp.new(no_minus + "\\b" + Regexp.quote(amount) + (unit ? "( |#{nbsp}| )(#{unit}|#{Regexp.quote(HTMLEntities.new.encode(unit, :named))})" :"\\b"))
expectation = negate ? :should_not : :should
page.body.send(expectation, match(regexp))
end
