(Thought question: ) Do you think that using float
instead of double saves a significant amount of computer
memory?
No. For most programs using variables of type double will use only
a few extra bytes.
This is insignificant
in a program thousands of bytes long.
Sometimes you need to explicitly ask for a single-precision float
literal.
Do this by putting a lower case f or upper case F at the end, like this:
123.0f
-123.5F
-198234.234f
0.00000381F
Sometimes you need to explicitly ask for a double
literal.
Do this by putting a lower case d or upper case D at the end, like this:
123.0d
-123.5D
-198234.234d
0.00000381D
Remember, that without any letter at the end, a floating point literal
will automatically be of type double.
