Floating Point Types

For floating point numbers, Haskell offers the Float and Double types. They are the direct equivalents of C's float and double types and thus represent 32-bit and 64-bit IEEE floating point numbers, respectively.

Again, you have the basic arithmetic operations, only this time, division is written as you'd expect.

Addition

GHCi

>>> 3.0 + 5.0
8.0

Subtraction

GHCi

>>> 3.0 - 5.0
-2.0

Multiplication

GHCi

>>> 3.0 * 5.0
15.0

Division

GHCi

>>> 3.0 / 5.0
0.6

Exponentiation

GHCi

>>> 3.0 ** 5.0
243.0

And we also have all the basic comparison operators at our disposal, just as for integers. For example,

GHCi

>>> 3.0 == 5.0
False
>>> 3.0 < 5.0
True
