@634 <Var> <Value>
The arc sine is formed from the value defined in <Value> and stored in <Var> as angle
value.
Example:
R35 = 0.70710678
@634 R17 R35
@637 <Var> <Value 1> <Value 2>
The numerical values defined in <Value 1> and <Value 2> are considered as vector
components. The result is the angle between the components given in <Value 2> and
the resultant vector.
Only one constant <Const> is allowed as operand for <Value1> and
The other operand must be a variable <Var>
Example:
R35 = 20 R36 = -30
@637 R17 R35
<
R36 = Value 2

(R parameter or pointer).
R36 The angle is formed from the vector components of the
contents of the parameters R35 and R36 and the result
(=146.30993) is entered/stored in R17.
