}
Output:
Error: domain error
The arccosine of -2.000000 is nan
The arccosine of 0.100000 is 1.470629
Calculates the trigonometric arc cosine function of a single precision
floating-point value.
<math.h>
float acosf (float x);
x
Returns the arc cosine in radians in the range of 0 to pi (inclusive).
A domain error occurs if x is less than -1 or greater than 1.
