Sin, cosine and tangent are expecting integers in Degrees mode (default)

[garycmartin]

If Calculate is set to Degrees mode (the default) it (incorrectly) expects an integer value for sin, cos, tangent. If you switch to Radians mode, floating point or integer values are accepted fine (thank goodness).

Error at 1: unsupported operand time (s) for *:'Decimal' and 'float'

Had no luck tracing this one down, the log lists a Runtime error but with no useful hints. Interestingly you can do sin(1/2) correctly, but not sin(0.5).
