Arith {frab}

Arithmetic methods for class "frab"

Description

The frab class provides basic arithmetic methods for frab objects. Low-level helper functions c_frab_eq() amd c_frab_pmax() are documented here for consistency; but technically c_frab_eq() is a Comparison operator, and c_frab_pmax() is an “Extremes” function. They are documented at Compare.Rd and pmax.Rd respectively.

Usage

frab_negative(x)
frab_reciprocal(x)
frab_plus_frab(F1,F2)
frab_multiply_numeric(e1,e2)
frab_power_numeric(e1,e2)
numeric_power_frab(e1,e2)
frab_unary(e1,e2)
frab_arith_frab(e1,e2)
frab_plus_numeric(e1,e2)
frab_arith_numeric(e1,e2)
numeric_arith_frab(e1,e2)

Arguments

e1, e2, x, F1, F2

Objects of class frab, coerced if needed

Value

Return frab objects

Examples

(x <- frab(c(a=1,b=2,c=3)))
(y <- frab(c(b=-2,d=8,x=1,y=7)))
(z <- frab(c(c=2,x=5,b=1,a=6)))


x+y
x+y+z

x*y
