R: Rounding of Numbers

round {photobiology} | R Documentation

## Rounding of Numbers

### Description

`ceiling` takes a single numeric argument x and returns a numeric vector containing the smallest integers not less than the corresponding elements of x. \ `floor` takes a single numeric argument x and returns a numeric vector containing the largest integers not greater than the corresponding elements of x. \ `trunc` takes a single numeric argument x and returns a numeric vector containing the integers formed by truncating the values in x toward 0. \ `round` rounds the values in its first argument to the specified number of decimal places (default 0). \ `signif` rounds the values in its first argument to the specified number of significant digits. \ The functions are applied to the spectral data, not the wavelengths. The quantity in the spectrum to which the function is applied depends on the class of `x` and the current value of output options.

### Usage

    ## S3 method for class 'generic_spct'
    round(x, digits = 0)

    ## S3 method for class 'generic_spct'
    signif(x, digits = 6)

    ## S3 method for class 'generic_spct'
    ceiling(x)

    ## S3 method for class 'generic_spct'
    floor(x)

    ## S3 method for class 'generic_spct'
    trunc(x, ...)

### Arguments

`x` | an object of class "generic_spct" or a derived class.
`digits` | integer indicating the number of decimal places (round) or significant digits (signif) to be used. Negative values are allowed (see ‘Details’).
`...` | arguments to be passed to methods.
