Public Class methods

epsilon()

The default distance from a Numeric below which it is considered to be approximately equal to a another Numeric.

epsilon=(epsilon)

Sets the default distance for approximately equals comparisons.

Public Instance methods

=~(value,epsilon=@@epsilon)

Alias for approximately_equals?

approximately_equals?(value,epsilon=@@epsilon)

returns true if the difference between the instance and the given Numeric is less than the given distance.

at_least(low=0)

Constrains a value to a lower limit.

at_most(high=0)

Constrains a value to an upper limit.

cut_rectify(high=1,low=0)

Treats the low and high as limits, returning low or high if the instance is respectively below or above these values, or the instance if between the two.

round_to_nearest(denominator=1)

Returns a numeric value such that any remainder is evenly divided by the given denominator.

with_fraction(denominator=1,separator='-',show_zero=false)

Renders a numeric value as a whole number and a fraction with a given denominator, separated with a given separator, and optionally showing fractions with a numerator of zero.

wrap_rectify(high=1,low=0)

Treats the interval between low and high as a cycle, returning the result of wrapping the instance around this interval.
