 Big complex number calculation library for Go (with [math/big](https://pkg.go.dev/math/big)).
@@ -12,14 +13,14 @@ Currently, the library supports:
 1. Gaussian integer, complex numbers whose real and imaginary parts are both integers:
 
 $$
-Z[i] = \{ a + bi \;|\; a, b \in \mathbb{Z} \}, \quad \text{where } i^2 = -1.
+Z[i] = \{ a + bi \ |\ a, b \in \mathbb{Z} \}, \quad \text{where } i^2 = -1.

 2. Hurwitz quaternion, quaternions whose components are either all integers or all half-integers (halves of odd
    integers; a mixture of integers and half-integers is excluded):
