Rounding of Numbers

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'

# 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

an object of class "generic_spct" or a derived class.
