Is it necessary to add f
to a float
value within the parameters of a if
?
Example:
if (a == 2.5f && a > 2.0f) {}

Nothing to do with if
, it's a matter of choosing literal you want to use .
If you want the number to be float
then you should use f
always. If it does not use and has a decimal point, it will default to double
. This type has 64 bits and float
has 32 bits. Then with the suffix f
or F
it will take up less memory space, and of course, it will have less precision.
If the number is integer, that is, it does not have a period in the literal, then it will not be double
, much less float
, unless you use f
.
In both there will be no accuracy, such as already shown in your previous question . If that's what you want, you can not use any of them. You need to create your own mechanism, use another form, or a library that treats this correctly.
