R: Real Vectors

real {base} | R Documentation

## Real Vectors

### Description

`real` creates a double precision vector of the specified length. Each element of the vector is equal to `0`.

`as.real` attempts to coerce its argument to be of real type.

`is.real` returns `TRUE` or `FALSE` depending on whether its argument is of real type or not.

### Usage

    real(length = 0)
    as.real(x, ...)
    is.real(x)

### Arguments

`length` | desired length.
`x` | object to be coerced or tested.
`...` | further arguments passed to or from other methods.

### Note

R has no single precision data type. All real numbers are stored in double precision format.
