|

By default, no math library will be provided by NuttX. In this this case, it
|
||
|
|
is assumed that (1) no math library is required, or (2) you will be using the
|
||
|
|
math.h header file and the libm library provided by your toolchain.
|
||
|
|
|
||
|
|
This is may be a very good choice is possible because your toolchain may have
|
||
|
|
have a highly optimized version of libm.
|
||
|
|
|
||
|
|
Another possibility is that you have a custom, architecture-specific math
|
||
|
|
libary and that the corresponding math.h file resides at arch/<architecture>/include/math.h.
|
||
|
|
The option is selected via ARCH_MATH_H. If ARCH_MATH_H is selected,then the include/nuttx/math.h
|
||
|
|
header file will be copied to include/math.h where it can be used by your applications.
|
||
|
|
|
||
|
|
If ARCH_MATH_H is not defined, then this option can be selected to build a generic,
|
||
|
|
math library built into NuttX. This math library comes from the Rhombus OS and
|
||
|
|
was written by Nick Johnson. The Rhombus OS math library port was contributed by
|
||
|
|
Darcy Gong.
