Hi,

I know that the limits of
- byte goes from -2^7 to 2^7-1
- char goes from 0 to 2^16
- int goes from -2^31 to 2^31-1

But what about float and double ?

Thanks in advance.

Pretty much -Double.MAX_VALUE to Double.MAX_VALUE and
-Float.MAX_VALUE to Float.MAX_VALUE, but no closer to zero than
approximately Double.MIN_VALUE and Float.MIN_VALUE.

Double.MAX_VALUE is 1.7976931348623157E308
Float.MAX_VALUE is 3.4028235E38
Double.MIN_VALUE is 4.9E-324
Float.MIN_VALUE is 1.4E-45
