Math Group Methods for Polynomials

Usage

Math.polynomial(x, digits)

Arguments

x An object of class polynomial
digits Precision, as required by round() or signif()

Description

Group method for functions in the Math group.

Details

Most math group functions are disallowed with polynomial arguments. The only exceptions are ceiling, floor, round, trunc, and signif which may be used to transform the coefficients accordingly.

Value

A polynomial with transformed coefficients.

op <- options(digits=18)
p <- poly.from.values(1:4, (2:5)^2)
## 1 + 2.00000000000001*x + x^2
p <- round(p)
## 1 + 2*x + x^2
options(op)
