module UnitMeasurements
module Math
# Rounds quantity of the measurement. If `ndigits` is not specified,
# quantity is rounded to `Integer`.
#
# @example
# UnitMeasurements::Weight.new(1, :g).convert_to(:st).round(4)
# => 0.0002 st
#
# @param [Integer] ndigits
#
# @return [Measurement]
def round(ndigits = 0)
self.class.new(quantity.round(ndigits), unit)
end
# Returns absolute value of the measurement quantity.
#
# @example
# UnitMeasurements::Length.new(-17.625, :m).abs
# => 17.625 m
#
# @return [Measurement]
def abs
self.class.new(quantity.abs, unit)
end
# Rounds quantity of the measurement to next lower integer.
#
# @example
# UnitMeasurements::Length.new(17.625, :m).floor
# => 17 m
#
# @return [Measurement]
def floor(*args)
self.class.new(quantity.floor(*args), unit)
end
# Rounds quantity of the measurement to next higher integer.
#
# @example
# UnitMeasurements::Length.new(17.625, :m).ceil
# => 18 m
#
# @return [Measurement]
def ceil(*args)
self.class.new(quantity.ceil(*args), unit)
end
