Does the map() function works on an ATtiny85?

Question

I have a working project on Arduino Uno.Now I want to shrink my project using an ATtiny85. Before purchasing an waiting for the shipment to arrive, I want to make sure that my whole code will run on ATtiny85.

specialy, will the map() function which is working on an Arduino Uno ( ATMEGA328P-PU ), work with a ATtiny85 Microcontroller?

You don't need to have the hardware in hand to try building code for it. — Chris Stratton, Jan 21 '15 at 17:34

The map function uses integer arithmetic, and since the ATmega series and the ATtiny series use the same 8-bit AVR instruction set, there should be no difference when using it, and you are good to go from that aspect.

Consider that there are many other differences regarding I/O pins, storage etc. - that you might want to consider. Here is a good source for a basic comparison between the ATmega based Arduino to ATtiny85.

Here is [the code that implements the map function](https://github.com/arduino/Arduino/blob/ide-1.5.x/hardware/arduino/avr/cores/arduino/WMath.cpp#L54-L57) – Gerben Jan 21 '15 at 15:57
