ACos

A command for Oblivion Script Extender

Syntax:

acos [float]

or

dacos [float]

Returns the arccosine of a number (i.e. the angle whose cosine this is)

Example

set n to ( r / x )
set theta to acos n

Notes

• From v0005, all OBSE trigonometric functions take and return degrees. Versions of the functions which accept radians are still available by prefixing the function name with an r. (i.e. racos)
• This function can be used in a mathematical formula (a + acos b), but a mathematical formula will not compile as the arguement for this function (acos (a + b) doesn't work).
• acos a + b = ( acos a ) + b
