atan2l - Linux
Overview
atan2l is a mathematical function that calculates the arctangent (angle) of two given arguments as a floating-point value. It is typically used to determine the direction or angle of a vector.
Syntax
double atan2l(long double y, long double x);
Options/Flags
None.
Examples
- Find the arctangent of the vector (3, 4).
$ atan2l(4, 3)
0.927295
- Calculate the direction of a point from the origin.
$ atan2l(8, 6)
0.982793
Common Issues
- Incorrect arguments: Ensure that both arguments are non-zero and of the correct type.
Integration
atan2l can be used in conjunction with other mathematical functions and libraries for advanced calculations, such as:
- Trigonometry: To calculate sine, cosine, or other trigonometric ratios.
