Arithmetic operations

Arithmetic operations including low-level helper functions

Usage

disord_inverse(a)
disord_mod_disord(a,b)
disord_mod_numeric(a,b)
disord_negative(a)
disord_plus_disord(a,b)
disord_plus_numeric(a,b)
disord_power_disord(a,b)
disord_power_numeric(a,b)
numeric_power_disord(a,b)
disord_prod_disord(a,b)
disord_prod_numeric(a,b)
disord_arith_unary(e1,e2)
disord_arith_disord(e1,e2)
disord_arith_numeric(e1,e2)
numeric_arith_disord(e1,e2)

Arguments

a,b

at least one is a disord object

e1,e2

Formal arguments for S4 dispatch

Details

Basic low-level arithmetic operations, intended to be called from S4 dispatch.

These functions return a disord object or a regular vector as appropriate. Consistency is required. The hash is set to be that of the disord object if appropriate.

Methods

signature(e1="numeric", e2="disord"): Dispatched to numeric_arith_disord()
