R: Math for ff vectors

abs.ff_vector {ffbase} | R Documentation

## Math for ff vectors

### Description

These mathematical functions implement `ff_vector` specific math and handle the following functions from the Math family:

- Math: `"abs", "sign", "sqrt", "ceiling", "floor", "trunc", "log", "log10", "log2", "log1p", "acos", "acosh", "asin", "asinh", "atan", "atanh", "exp", "expm1", "cos", "cosh", "sin", "sinh", "tan", "tanh", "gamma", "lgamma", "digamma", "trigamma"`

- Math2: `"round", "signif"`

The operators require `x` to be an `ff_vector`.
