1. (mathematics) asymptotically equal to

   • n! ≃ ${\displaystyle {\sqrt {2\pi n}}\left({\frac {n}{e}}\right)^{n}}$
   • ${\displaystyle \pi (N){\text{≃}}{\frac {N}{\log(N)}}}$ , where ${\displaystyle \pi (N)}$ is the prime-counting function which is the number of primes less than or equal to N.

2. (mathematics) is approximately equal to

   • π ≃ 3.14159
   • ${\displaystyle {\tfrac {8}{9}}}$ ≃ 0.889
   • ${\displaystyle {\tfrac {2}{3}}}$ ≃ 0.667
   • ${\displaystyle {\tfrac {1}{9}}}$ π² ≃ 1.097
   • ${\displaystyle {\tfrac {1}{12}}}$ π² ≃ 0.822
