Answer / gurmeet singh
A variable of type float only has 7 digits of precision
where as a variable of type double has 15 digits of
precision. If you need better accuracy, use double instead
of float.

Answer / brianmanee
The Decimal, Double, and Float variable types are different
in the way that they store the values. Precision is the
main difference where float is a single precision (32 bit)
floating point data type, double is a double precision (64
bit) floating point data type and decimal is a 128-bit
floating point data type.

Answer / sanah
In Computer Science terminology(world) Real numbers are those which have decimal points.
These real numbers are categorized in 2 ways.
1.Float and
2.Double
Memory used by these two differs based on the programming language on which we works.
For Example in C:-
Float:-It uses only 4 bytes of memory
Double:-It uses 8 bytes of memory
The only difference between these two is that---
Float can hold only 4 bytes(ex:2.4509)
Double is used to hold 8 bytes(ex:2.450877777777777777779)
i.e
if(real_no is larger)
{
we go for double;//remember double is a real
}
else
{
we go for float;//remember float is also a real
}
