LNUM_FLOAT Problematic. Math functions not ANSI C. Limited or no

The only benefit I see is less memory consumption on embedded
devices (speedwise, not much difference with LNUM_DOUBLE+LNUM_INT32).
Is anyone actually using 'float' currently, and what is the main
reason you do?
Agree with others, float is important from a memory perspective and to
a lesser extent execution time. As a matter of interest on an ARM9 at
200MHz the difference between float on double in microsec is:
float op float double
* 12 15
/ 12 22 very significant
+ 10 13
– 10 13
(long) to ... 10 10
