A relational symbol indicating "greater than and approximately equal to" commonly used in numerical analysis and inequalities.
Examples
Comparing approximate values
f(x) \gtrapprox 5.7 \text{ for } x > 3
Asymptotic behavior
n^2 + n \gtrapprox n^2 \text{ for large } n
Numerical inequality with uncertainty
\sqrt{10} \gtrapprox 3.16 \gtrapprox \pi
