Atan Procedure

Returns the arc tangent of the number, in radians.

Warning: The input number is internally converted to a less precise 64-bit binary floating-point format. The result is computed in this format and then converted back to TMBASIC's 128-bit decimal floating-point format. These conversions may cause a loss of precision.
