operators_bigq

Basic arithmetic operators for large rationals

Description

Addition, subtraction, multiplication, division, and absolute value for large rationals, i.e. "bigq" class R objects.

Usage

add.bigq(e1, e2)
## S3 method for class 'bigq'
e1 + e2

sub.bigq(e1, e2=NULL)
## S3 method for class 'bigq'
e1 - e2

mul.bigq(e1, e2)
## S3 method for class 'bigq'
e1 * e2

div.bigq(e1, e2)
## S3 method for class 'bigq'
e1 / e2

## S3 method for class 'bigq'
e1 ^ e2

## S3 method for class 'bigq'
abs(x)

Arguments

e1,e2, x

of class "bigq", or (e1 and e2) integer or string from an integer

Details

Operators can be use directly when the objects are of class "bigq": a + b, a * b, etc, and a ^ n, where n must be coercable to a biginteger ("bigz").

Value

A bigq class representing the result of the arithmetic operation.

Author(s)

Immanuel Scholz and Antoine Lucas

Examples

## 1/3 + 1 = 4/3 :
as.bigq(1,3) + 1

r <- as.bigq(12, 47)
stopifnot(r ^ 3 == r*r*r)
