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

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

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

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

@example
var bool = isNonNegativeFinite( 0.0 );
// returns true

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

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

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