Hi,
This is my attempt to comply with the tests Matthew posted last night.
#!/usr/bin/ruby
def bodgy_rounding(amt)
if amt >= 0.0
x = amt % 5.0
y = amt - x
round = x > 2.0 ? y+5 : y
rem = round - amt
elsif amt > -3.0
rem = 0.0 - amt
round = 0.0
else
rem = 0.0
round = amt
end
return [round, rem]
end
This is how I'd code this:
$cat nrs_payroll.rb
def bodgy_rounding(x)
remainder = x % 5.0
base_amount = x - remainder
remainder > 2 ? (return base_amount+5):(return base_amount)
end
$cat simple_br_test.rb
#!/usr/bin/env ruby
require 'test/unit'
require 'nrs_payroll.rb'
class SimpleBodgyRoundingTest < Test::Unit::TestCase
def test_bodgy_rounding
assert_equal(10, bodgy_rounding(12))
assert_equal(15, bodgy_rounding(13))
assert_equal(0, bodgy_rounding(1))
assert_equal(0, bodgy_rounding(0))
assert_equal(5, bodgy_rounding(7))
assert_equal(10, bodgy_rounding(7.01))
end
def test_negative_bodgy_rounding
assert_equal(0, bodgy_rounding(-1))
assert_equal(0, bodgy_rounding(0))
assert_equal(0, bodgy_rounding(-2))
assert_equal(-5, bodgy_rounding(-3))
# assert_equal(-7.39, bodgy_rounding(-7.39))
assert_equal(-10, bodgy_rounding(-10))
# assert_equal(-71.39, bodgy_rounding(-71.39))
# assert_equal(-72.39, bodgy_rounding(-72.39))
# assert_equal(-73.39, bodgy_rounding(-73.39))
# assert_equal(-74.39, bodgy_rounding(-74.39))
end
end
Then, run
$./simple_br_test.rb
Output:
