Returns the minimum single-precision floating-point number.

@param {number} x - first number
@param {number} y - second number
@returns {number} minimum value

@example
var v = minf( 3.14, 4.2 );
// returns 3.14

@example
var v = minf( 3.14, NaN );
// returns NaN

@example
var v = minf( +0.0, -0.0 );
// returns -0.0
