Modern as in modern desktop / server hardware?  No.  In fact floats  
may cause a slight penalty due to conversions in and out of double.   
Depending on your application (and struct alignment) you _might_ get  
better cache use from float.

Embedded processors, consoles, set tops, mobile phones, all of these  
might be better using float.
