bigq: Large sized rationals

Description

Type class supporting arithmetic operations on very large rationals.

Usage

as.bigq(n, d = 1)
as.character.bigq(x,b=10,...)
as.double.bigq(x,...)
as.bigz.bigq(a,mod=NA)
is.na.bigq(x)
print.bigq(x,...)
denominator(x)
numerator(x)

Arguments

n,d

Either integer, numeric or string value (String value: ither starting with 0x for hexadecimal, 0b for binary or without prefix for decimal values. Any format error results in 0). n stands for numerato

a

An element of class bigq

mod

Optional modulus to convert into biginteger

x

Numeric value

b

Base: from 2 to 32

...

Additional parameters

Value

• A bigq class representing the parameter value.

Details

Examples

x <- as.bigq(21,6)
x
# 7 / 2
# Wow ! result is simplified.

y <- as.bigq(5,3)

# addition work !
x + y

# You can even try multiplication, division...
x * y / 13 

# convert to string, double
as.character(x)
as.double(x)
