Standard math functions for parameter expressions.

bumps.pmath.acos(*args)

bumps.pmath.acosd(*args: Parameter | Expression | Calculation | float)

  Return the arc cosine (measured in in degrees) of x.

bumps.pmath.acosh(*args)

bumps.pmath.arccosd(*args: Parameter | Expression | Calculation | float)

  Return the arc cosine (measured in in degrees) of x.

bumps.pmath.arcsind(*args: Parameter | Expression | Calculation | float)

  Return the arc sine (measured in in degrees) of x.

bumps.pmath.arctan2d(*args: Parameter | Expression | Calculation | float)

bumps.pmath.atan(*args)

bumps.pmath.atan2(*args)

bumps.pmath.atan2d(*args: Parameter | Expression | Calculation | float)

  Return the arc tangent (measured in in degrees) of y/x. Unlike atan(y/x), the signs of both x and y are considered.

bumps.pmath.atand(*args: Parameter | Expression | Calculation | float)

  Return the arc tangent (measured in in degrees) of x.

bumps.pmath.atanh(*args)

bumps.pmath.cosd(*args: Parameter | Expression | Calculation | float)

  Return the cosine of x (measured in in degrees).

bumps.pmath.max(Parameter)

bumps.pmath.min(Parameter)

bumps.pmath.sind(*args: Parameter | Expression | Calculation | float)
