ATN / ATN2
Acquires the arctangent of the specified value
Format
ATN (expression)
Format
ATN2 (expression 1, expression 2)
Explanation
ATN:
Acquires the arctangent values of the specified <
expression>
values. The
acquired values are radians within the following range: -
π
/ 2 to +
π
/ 2
ATN2:
Acquires the arctangent values of the specified <
expression 1>
and
<
expression 2>
X-Y coordinates. The acquired values are radians within
the following range: -
π
to +
π
SAMPLE
A(0)=A*ATN(Y/X) ················· The product of the expression (Y/X)
arctangent value and variable A is
assigned to array A (0).
A(0)=ATN(0.5) ··················· The 0.5 arctangent value is assigned
to array A (0).
A(0)=ATN2(B,C)-D ················ T h e d i f f e r e n c e b e t w e e n t h e X - Y
coordinates (B,C) arctangent value and
variable D is assigned to array A (0).
A(1)=RADDEG(ATN2(B,C)) ·········· The X-Y coordinates (B,C) arctangent
value is converted to degrees, and is
then assigned to array A (1).
