function isPositiveFinite( x ) {
	return ( x > 0.0 && x < PINF );
}
Tests if a double-precision floating-point numeric value is a positive finite number.

@param {number} x - value to test
@returns {boolean} boolean indicating whether the value is a positive finite number

@example
var bool = isPositiveFinite( 5.0 );
// returns true

@example
var bool = isPositiveFinite( 3.14 );
// returns true

@example
var bool = isPositiveFinite( 0.0 );
// returns false

@example
var bool = isPositiveFinite( Infinity );
// returns false

@example
var bool = isPositiveFinite( -3.14 );
// returns false

@example
var bool = isPositiveFinite( NaN );
// returns false
