Hi,
I have been using math functions from math.h redlib. While i consider upgrading to lpcxpresso 5, i find several math functions that were previously available in redlib lpcxpresso release 4.1.0 are missing now in the latest release. Examples are round( ), atan2f( ) etc...
I know newLib is there. But why redlib has reduced its features? Or am i missing something?

There were a number of C99 function declarations accidentally added to the Redlib math.h header file in early LPCXpresso v4 builds where no actual definition exists in the library itself. More details of this can be found in this post...

These declarations have since been removed from math.h.

In my case, atan2f( ) is the C99 function precisely i use. It has been defined under version 4.1.0 (i am quite sure) and i have been using that in my project :eek:. Somehow it has been omitted in later versions.
But according to the suggestion, i am now using newlib without any problems.:)
Thanks.
