angle

sisl.utils.angle(s: str, rad: bool = True, in_rad: bool = True) → float

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

Parameters:

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

• in_rad – 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
