abs(_:)

Returns the absolute value (magnitude, modulus) of z.
Declaration
Swift
```
public func abs<T>(_ z: Complex<T>) -> Complex<T>
```

`sqrt(_:)`

Returns the square root of z.

Declaration

Swift

public func sqrt<T>(_ z: Complex<T>) -> Complex<T>

abs(_:)

Returns the absolute value (magnitude) of x.
Declaration
Swift
```
public func abs<T>(_ x: Rational<T>) -> Rational<T>
```
ceil(_:)

Returns the closest integral value greater than or equal to x.
Declaration
Swift
```
public func ceil<T>(_ x: Rational<T>) -> Rational<T>
```
floor(_:)

Returns the closest integral value less than or equal to x.
Declaration
Swift
```
public func floor<T>(_ x: Rational<T>) -> Rational<T>
```
round(_:)

Returns the closest integral value; if two values are equally close, returns the one with greater magnitude.
Declaration
Swift
```
public func round<T>(_ x: Rational<T>) -> Rational<T>
```
trunc(_:)

Returns the closest integral value with magnitude less than or equal to that of x.
Declaration
Swift
```
public func trunc<T>(_ x: Rational<T>) -> Rational<T>
```
