# routine floor

Documentation for routine `floor`

assembled from the following types:

# class Complex

From Complex

## (Complex) method floor

Defined as:

method floor(Complex: --> Complex)

Returns `self.re.floor + self.im.floor`

. That is, each of the real and imaginary parts is rounded to the highest integer not greater than the value of that part.

say (1.2-3.8i).floor; # OUTPUT: «1-4i»

# class Cool

From Cool

## (Cool) routine floor

Defined as:

multi sub floor(Numeric(Cool))multi method floor

Coerces the invocant (or in sub form, its argument) to Numeric, and rounds it downwards to the nearest integer.

say "1.99".floor; # OUTPUT: «1»say "-1.9".floor; # OUTPUT: «-2»say 0.floor; # OUTPUT: «0»

# role Rational

From Rational

## (Rational) method floor

Defined as:

method floor(Rational: --> Int)

Return the largest integer not greater than the invocant. If denominator is zero, fails with `X::Numeric::DivideByZero`

.

# role Real

From Real

## (Real) method floor

method floor(Real --> Int)

Return the largest integer not greater than the number.
