```{index} single: bsqrt; Math::GMP function ``` ```{index} single: Math::GMP::bsqrt; Perl function ``` # bsqrt Return the integer square root of `$x`. ## Synopsis ```perl Math::GMP->new(6)->bsqrt; # 2 — int(sqrt(6)) Math::GMP->new(49)->bsqrt; # 7 ``` Equivalent to `broot(2)` but noticeably faster. Croaks on negative arguments inside `libgmp`.
