Check if a variable is of (non-integer) double type or a whole number

is_float() checks whether an input vector or value is a numeric non-integer (double), depending on fractional parts of the value(s). is_whole() does the opposite and checks whether an input vector is a whole number (without fractional parts).

is_float(x)

is_whole(x)

Arguments

x

A value, vector or data frame.

Value

For is_float(), TRUE if x is a floating value (non-integer double), FALSE otherwise (also returns FALSE for character vectors and factors). For is_whole(), TRUE if x is a vector with whole numbers only, FALSE otherwise (returns TRUE for character vectors and factors).

Examples

data(mtcars)
data(iris)

is.double(4)
#> [1] TRUE
is_float(4)
#> [1] FALSE
is_float(4.2)
#> [1] TRUE
is_float(iris)
