You're developing an embedded system with constrained memory. What should be the main consideration when choosing between using float and double data types? 

  • Precision needs 
  • Popularity of type 
  • Storage size requirement 
  • Arithmetic operations
In embedded systems with memory constraints, storage size becomes a primary concern. A float generally occupies 4 bytes, while a double occupies 8 bytes. Hence, if precision offered by float is acceptable for the application, it would be preferable to use float to save memory space.
