# f64
`````{roto:type} f64
The 64-bit floating point type.
`````


````{roto:function} abs(self: f64) -> f64
Computes the absolute value of self.
````

````{roto:function} ceil(self: f64) -> f64
Returns the smallest integer greater than or equal to self.
````

````{roto:function} floor(self: f64) -> f64
Returns the smallest integer greater than or equal to self.
````

````{roto:function} is_finite(self: f64) -> bool
Returns true if this number is neither infinite nor NaN.
````

````{roto:function} is_infinite(self: f64) -> bool
Returns true if this value is positive infinity or negative infinity, and false otherwise.
````

````{roto:function} is_nan(self: f64) -> bool
Returns true if this value is NaN.
````

````{roto:function} pow(self: f64, exp: f64) -> f64
Raises a number to a floating point power.
````

````{roto:function} round(self: f64) -> f64
