of the operands is ØÖÙ (1). Ð ÜÓÖ Ð return ØÖÙ (1) if exactly one of both operands is true.
ÒÓØ Ð returns ØÖÙ (1) if the input is Ð× (0), and Ð× (0), if the input is ØÖÙ (1).
3.5.10 Trigonometric Functions
All these functions work on tuples of numbers as arguments. The input can either be of type
ÒØÖ or ÖÐ. However, the resulting type will be of type ÖÐ. The functions are applied
to all tuple values and the resulting tuple has the same length as the input tuple. For ØÒ¾
the two input tuples have to be of equal length. Table 3.15 shows the provided trigonometric
×Ò´µ sine of
Ó×´µ cosine of
ØÒ´µ tangent of
×Ò´µ arc sine of in the intervall [ ¾¾℄, ¾ ½ ½]
Ó×´µ arc cosine in the intervall [ ¾¾℄, ¾ ½ ½]
ØÒ´µ arc tangent in the intervall [ ¾¾℄, ¾ ½ ½]

3.5.11 Exponential Functions
All these functions work on tuples of numbers as arguments. The input can either be of type
ÒØÖ or ÖÐ. However, the resulting type will be of type ÖÐ. The functions are applied
to all tuple values and the resulting tuple has the same length as the input tuple. For ÔÓÛ
and ÐÜÔ the two input tuples have to be of equal length. Table 3.16 shows the provided

3.5.12 Numerical Functions
The functions ÑÒ and ÑÜ select the minimum and the maximum values of the tuple values.
All values either have to be of type ×ØÖÒ, orÒØÖ/ÖÐ. It is not allowed to mix strings
