1.11 + File Name: 15.8.2.4.js
1.12 + ECMA Section: 15.8.2.4 atan( x )
1.13 + Description: return an approximation to the arc tangent of the
1.14 + argument. the result is expressed in radians and
1.15 + range is from -PI/2 to +PI/2. special cases:
1.16 + - if x is NaN, the result is NaN
1.17 + - if x == +0, the result is +0
1.18 + - if x == -0, the result is -0
1.19 + - if x == +Infinity, the result is approximately +PI/2
1.20 + - if x == -Infinity, the result is approximately -PI/2
