function validateRealFloating( value ) {
	return isNumber( value );
}
Verifies whether a provided value can be safely cast to a real-valued floating-point data type.

@private
@param {*} value - input value
@param {string} dtype - data type
@returns {boolean} boolean result

@example
var out = validateRealFloating( 3.14, 'float64' );
// returns true

@example
var Complex128 = require( '@stdlib/complex/float64/ctor' );

var out = validateRealFloating( new Complex128( 5.0, 6.0 ), 'float64' );
// returns false
