Trigonometric and hyperbolic functions: sin. I know this is definitely possible as I've seen places that do have fixed point atan2 functions such as MathFP for Java and Allegro's fixatan2(fixed y, fixed x). Example The C function atan2, and most other computer implementations, are designed to reduce the effort of transforming cartesian to polar coordinates and so always define atan2(0, 0). atan2(y,x) has that discontinuity at 180° where it switches to -180°. POSIX specifies that in case of underflow, y/x is the value returned, and if that is not supported, and implementation-defined value no greater than DBL_MIN, FLT_MIN, and LDBL_MIN is returned.

The return value is in the range -π to π.

Effects of Locale : Actions affected by the choice of locale.

musl is an implementation of the C standard library built on top of the Linux system call API, including interfaces defined in the base language standard, POSIX, and widely agreed-upon extensions. h library can be divided into three main categories i. function computes four-quadrant inverse tangent of elements of two vectors.

Choosing Locale : How the user specifies a locale.Purpose of Implementation Planning [Describe the purpose of the Implementation Planning. MPLAB® XC8 C Compiler User's Guide for PIC® MCU 9. I recently implemented tan, cot, atan, atan2 using SSE2 intrinsics, which serve as extensions to the SSE2 implementations of sin, cos, exp, log by Julien Pommier. The C library function double atan2(double y, double x) returns the arc tangent in radians of y/x based on the signs of both values to determine the correct quadrant.
