/**
* Computes the inverse cotangent of a single-precision floating-point number.
*
* ## Method
*
* ```text
* \operatorname{acotf}(x) = \operatorname{atanf}(\frac{1}{x})
* ```
*
* @param {number} x - input value
* @returns {number} inverse cotangent (in radians)
*
* @example
* var v = acotf( 2.0 );
* // returns ~0.4636
*
* @example
* var v = acotf( 0.0 );
* // returns ~1.5708
*
* @example
* var v = acotf( 0.5 );
* // returns ~1.1071
*
* @example
* var v = acotf( 1.0 );
* // returns ~0.7854
*
* @example
* var v = acotf( NaN );
* // returns NaN
*
* @example
* var v = acotf( Infinity );
* // returns 0.0
