Syntax: |
vout = ATAN2( v1, v2 )
|
The ATAN2(v1,v2)
function returns the
Arc Tangent of v1/v2
, with
-π < ATAN2(v1,v2) ≤
π.
v1 > 0
, the result is positive.v1 = 0
, the result is zero if
v2 > 0
and π if
v2 < 0
.v1 < 0
, the result is negative. If the value of
the second argument is zero, the absolute value of the result is π/2
.Both arguments must not have the value zero.
