Arduino fpu library - NUCLEO-F746ZG Mbed
Unlike other platforms, where you can get more precision by using a double (e. g. up to 15 digits), on the Arduino, double is the same size as float.
The oscilloscope showing analog input and digital output from an Arduino Uno powering a servo speed and a FPU for Adafruit Neopixel library to.
Version 3. 5 features a 32 bit 120 MHz ARM CortexM4 processor with floating point unit. Please note: Teensy 3 boards are not official Arduinobrand products.
(The lack of fpu probably does make a I think the cryptosuite library combined with the ArduinoPusherClient library was just too much, and the Arduino was running.
