[avr-libc-dev] Possible bug in avr-libc documentation

[Christian Hachmann]

Hi
The documenation of the Mathematics-Module reads

      double asin  (  double    __x  )   
         The asin() function computes the principal value of the arc sine of x. 
The returned value is in the range [0, pi] radians. A domain error occurs for 
arguments not in the range [-1, +1]. 
     


While the funktion in avr-libc itself seems to me to work properly and returns 
values in the range [-pi/2,pi/2] the documentation names a range of [0,pi] 
which doesn't make sense esp. for negative arguments.
