|
|
By default, no math library will be provided by NuttX. In this
|
|
case, it is assumed that (1) no math library is required, or (2) you
|
|
will be using the math.h and float.h headers 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 library and that the corresponding math.h file resides at
|
|
arch/<architecture>/include/math.h. The option is selected via
|
|
CONFIG_ARCH_MATH_H. If ARCH_MATH_H is selected,then the
|
|
include/nuttx/libmath.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.
