This chapter describes the functions that are globally available in all scripts written in the Antares DSL programming language.
Arithmetic Functions
/**
* Computes the binary logarithm (base 2) of a given value.
*
* The result is rounded up to the next bigger integer value in order to
* provide enough bits when used to calculate the number of necessary bits that
* represent a number whose number of bits is given by [value].
*
* Examples:
* - log2(8) = 3
* - log2(10) = 4
* - log2(16) = 4

/**
* Extracts [size] bits at position [pos] from [signal], where bit positions start with 0.
*
* Example: bits(31, 3, 2) = 3.

private fun bits(signal: DigitalSignal, pos: Long, size: Long): Long
/**
* Treats [signal] like an input signal to a logic gate, thereby possibly converting
* undefined (floating) bits according to the current system preference
* "Undefined Gate Input Behaviour".
*
* Example: gated(I) returns 0 if I is 0x?8 and "Undefined Gate Input Behaviour"
* is "Read as O"
