void abort(void);
The abort function is usually called by the assert macro. If you use assert s in your
application, you might want to permanently place a breakpoint in abort() to simplify
debugging when assert s fail.

ior is undefined.


int abs(int j);
Returns
The absolute value.
Example
int I=-5632;

int j;

j=abs(I);
acos
Computes the principal value of the arc cosine of x . A domain error occurs for arguments
not in the range [-1,+1].
Synopsis
#include

double acos(double x);
Returns
The arc cosine in the range [0, pi].
