add.bigz: Basic arithmetic operators for large integers

Description

Addition, substraction, multiplication, division, remainder of division, multiplicative inverse, power and logarithm functions.

Usage

add.bigz(a, b)
a + b (if a or b is a bigz vector)
sub.bigz(a, b)
a - b (if a or b is a bigz vector)
mul.bigz(a, b)
a * b (if a or b is a bigz vector)
div.bigz(a, b)
a / b (if a or b is a bigz vector)
mod.bigz(a, b)
a %% b (if a or b is a bigz vector)
inv.bigz(a, b,...)
inv(a, ...)
pow.bigz(a, b,...)
pow(a, ...)
a ^ b (if a or b is a bigz vector)
log.bigz(x, base=exp(1))
log(a, base=exp(1)) (if a is a bigz vector)
log2.bigz(a)
log2(a) (if a is a bigz vector)
log10.bigz(a)
log10(a) (if a is a bigz vector)

Arguments

x

bigz, integer or string from an integer

a

bigz, integer or string from an integer

b

bigz, integer or string from an integer

base

base of the logarithm; base e as default

...

Additional parameters

Value

• A bigz class representing the result of the arithmetic operation.
