Returns the arccosine of a float in radians.
var = ACOS( x )
A floating point variable such as single or double, that is assigned with the ACOS of variable x.
The float to get the ACOS of. Input is valid from –1 to +1 and returns
p to 0.
If Input is < -1 than p and input is > 1 than 0 will returned.
If Input is cause of rounding effect in float-operations a little bit over 1 or -1, the value for 1.0 (-1.0) will be returned. This is the reason to give the value of the limit-point back, if Input is beyond limit. Generally the user have to take care, that Input to this function lies within –1 to +1.
All trig functions work with radians. Use deg2rad and rad2deg to convert between radians and angles.
