bc.d

Broadcasted Decimal Numeric Operations

Description

The bc.d() function performs broadcasted decimal numeric operations on 2 numeric or logical arrays.
bc.num() is an alias for bc.d().

Usage

bc.d(x, y, op, tol = sqrt(.Machine$double.eps))

bc.num(x, y, op, tol = sqrt(.Machine$double.eps))

Arguments

x, y	conformable logical or numeric arrays.
op	a single string, giving the operator. Supported arithmetic operators: +, -, *, /, ^, pmin, pmax. Supported relational operators: ==, !=, <, >, <=, >=, d==, d!=, d<, d>, d<=, d>=.
tol	a single number between 0 and 0.1, giving the machine tolerance to use. Only relevant for the following operators: d==, d!=, d<, d>, d<=, d>= See the %d==%, %d!=%, %d<%, %d>%, %d<=%, %d>=% operators from the ‘tinycodet’ package for details.

Value

For arithmetic operators:
A numeric array as a result of the broadcasted decimal arithmetic operation.

For relational operators:
A logical array as a result of the broadcasted decimal relational comparison.

Examples

library("broadcast")

x.dim <- c(4:2)
x.len <- prod(x.dim)
x.data <- sample(c(NA, 1.1:1000.1), x.len, TRUE)
x <- array(x.data, x.dim)
y <- array(1:50, c(4,1,1))
