If the value of Avagadro constant is 6.023 x 10 power 23, then what data type should we use to store this info?
float
double
long
None of the above
Correct Answer : A
The value to be stored must fall in the range of datatype to be used and among the suitable datatypes the one with minimal space is selected.
Range of float : 1.40e-45 to 3.40e+38
Range of double : 4.9e-324 to 1.8e+308
Range of long : -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 long is not suitable. float and double are suitable. In order to save space we use float.
Size of double in bits
