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.

Could you please fill out a bug tracker for this? That way it doesn't get lost.
