angle

sisl.utils.angle(s, rad=True, in_rad=True)

Convert the input string to an angle, either radians or degrees.

Parameters:

s : str

If s starts with ‘r’ it is interpreted as radians [0:2pi]. If s starts with ‘a’ it is interpreted as a regular angle [0:360]. If s ends with ‘r’ it returns in radians. If s ends with ‘a’ it returns in regular angle.

s may be any mathematical equation which can be intercepted through eval.

rad : bool, optional

Whether the returned angle is in radians. Note than an ‘r’ at the end of s has precedence.

in_rad : bool, optional

Whether the calculated angle is in radians. Note than an ‘r’ at the beginning of s has precedence.

Returns:

float

the angle in the requested unit
