I just don't understand how the table was created.
In case of arc_table[01], you commented that 26.565 degrees -> atan(2^-1).
So the binary is the floating 32 single (sign/exponent/mantisa) of 26.565 or atan(2^-1)?

Thank you

y=atan(x)/(2 * 4 * atan(1)) *(2^32);
this is normalisation of the range [-pi , pi ) to [0,1) * 2^32 represented in binary

atan (1)*4 = pi
