Posted on May 17, 2011 at 14:32Since Floating Point requires very significantly more resources (memory space, execution time, etc) than integer maths - especially on a chip like the STM32 with no hardware FPU - it is often best avoided on (small) microcontrollers.
For this reason, many (most?) embedded toolsets disable floating point by default.
Therefore, the first thing you really need to ask yourself is,
''do I really need floating point?''
eg, instead of
float volts;
volts = 1.6483; you could have:
int millivolts;
millivolts = 16483;
Otherwise, you are going to have to consult your Raisonance
manuals to find out about their support for floating point...
