Numeric Predicates

Description

Check numeric objects:

• is_zero() checks if an object contains only zeros.

• is_odd() and is_even() check if a number is odd or even, respectively.

• is_positive() and is_negative check if an object contains only (strictly) positive or negative numbers.

• is_whole() checks if an object only contains whole numbers.

Usage

is_zero(x, tolerance = sqrt(.Machine$double.eps), ...)

is_odd(x, ...)

is_even(x, ...)

is_positive(x, strict = FALSE, ...)

is_negative(x, strict = FALSE, ...)

is_whole(x, tolerance = sqrt(.Machine$double.eps), ...)

Arguments

x	A numeric object to be tested.
tolerance	A numeric scalar giving the tolerance to check within.
...	Currently not used.
strict	A logical scalar: should strict inequality be used?

Value

A logical vector.
