/**
* Evaluates the quantile function for a uniform distribution with minimum support `a` and maximum support `b` at a probability `p`.
*
* @private
* @param {Probability} p - input value
* @param {number} a - minimum support
* @param {number} b - maximum support
* @returns {number} evaluated quantile function
*
* @example
* var y = quantile( 0.8, 0.0, 1.0 );
* // returns 0.8
*
* @example
* var y = quantile( 0.5, 0.0, 10.0 );
* // returns 5.0
*
* @example
* var y = quantile( 1.1, 0.0, 1.0 );
* // returns NaN
*
* @example
* var y = quantile( -0.2, 0.0, 1.0 );
* // returns NaN
*
* @example
* var y = quantile( NaN, 0.0, 1.0 );
* // returns NaN
*
* @example
* var y = quantile( 0.0, NaN, 1.0 );
* // returns NaN
*
* @example
* var y = quantile( 0.0, 0.0, NaN );
* // returns NaN
*
* @example
* var y = quantile( 0.5, 2.0, 1.0 );
* // returns NaN
