darctan

Returns the inverse tangent of x. This will accept any number as, unlike dtan(), darctan() asymptotes are on the y axis so it just means you'll never get returned a number greater than 90 or less than -90.

NOTE: This function returns a value in degrees, not radians.

Syntax:

darctan(x);

Returns:

Real

Example:

val = darctan(1);

This will set "val" to -45.
