## Miscellaneous Mathematical Functions

### Description

`abs(x)` computes the absolute value of `x`, `sqrt(x)` computes the (principal) square root of `x`. 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'
    sqrt(x)

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

### Arguments

`x` | an object of class "generic_spct"

### See Also

Other math operators and functions: `^.generic_spct`, `convolve_each`, `div-.generic_spct`, `log`, `minus-.generic_spct`, `mod-.generic_spct`, `plus-.generic_spct`, `round`, `sign`, `slash-.generic_spct`, `times-.generic_spct`
