atan.c (7265, 1999-11-25)
Dear user,
this package contains 2 files :
- readme.txt (you read it right now !)
- atan.c
atan.c calculates the arctangent of the input values x and y (sometimes called atan2)
by using a CORDIC (COordinate Rotation on a DIgital Computer) algorithm.
It uses a itterative method and only shift, add and substract operations, so its fast
implementation to C with no floating point arithmetics is easy.
Attention ! Although the c-function and the table are written with a few lines, the
compilation results in about 1,7KByte of binary code because of using long ints !
Questions and/or suggestions are welcome.
Regards, Thorsten Godau
