Logic: Logic Operators for Comparing Dual Numbers

Description

These functions provide the operators for logical comparisons between dual numbers. These operators are designed to test equality and inequalities (such as "not equal", "greater", "less", "greater or equal", "less or equal").

Usage

# S4 method for dual,numeric
==(e1, e2)
# S4 method for numeric,dual
==(e1, e2)
# S4 method for dual,dual
==(e1, e2)
# S4 method for dual,numeric
!=(e1, e2)
# S4 method for numeric,dual
!=(e1, e2)
# S4 method for dual,dual
!=(e1, e2)
# S4 method for dual,numeric
>(e1, e2)
# S4 method for numeric,dual
>(e1, e2)
# S4 method for dual,dual
>(e1, e2)
# S4 method for dual,numeric
>=(e1, e2)
# S4 method for numeric,dual
>=(e1, e2)
# S4 method for dual,dual
>=(e1, e2)
# S4 method for dual,numeric
<(e1, e2)
# S4 method for numeric,dual
<(e1, e2)
# S4 method for dual,dual
<(e1, e2)
# S4 method for dual,numeric
<=(e1, e2)
# S4 method for numeric,dual
<=(e1, e2)
# S4 method for dual,dual
<=(e1, e2)

Value

The correspondent boolean/logical value of the comparison between e1 and e2 is returned.

Arguments

e1

dual object or numeric value.

e2

dual object or numeric value.

Examples

x <- dual(1.5, 1:0)
y <- dual(2.6, 0:1)
x == y
x != y
x > y
x >= y
x < y
x <= y
