认领这个 Plugin →Complex-number math toolbox for DeepSeek Harness (dsh). Five pure-math tools that do complex arithmetic correctly on the principal branch, so the agent never has to hand-track i² = -1 bookkeeping, Euler formulas, or polar conversions.
中文简介：dsh-complex 是 DeepSeek Harness 的复数数学工具箱插件，提供 5 个纯计算工具（复数解析、四则运算与整数幂、极坐标↔直角坐标互转、初等复函数主值、n 次方根全集），零运行时依赖、纯本地算术。适合让 Agent 直接完成「复数乘除、极坐标转换、欧拉公式、n 次方根、主值分支」等手算极易出错的计算。
LLMs reliably botch complex arithmetic: (3+4i)(1-2i), exp(iπ), log(-1), √-4, the four fourth roots of 1, i^i. This plugin computes them exactly (IEEE double, output rounded to 10 decimals by default) with deterministic closed-form formulas, anchored by the Python stdlib cmath reference implementation in tests.
| Tool | What it does |
|---|---|
complex_parse | Parse "3+4i", "-2i", "1e3+2e-1j" (i or j, implicit coefficient 1 accepted) or polar "5∠53.13°" (degrees) into a full identity: rectangular/polar/exponential forms, modulus, argument (rad + deg), conjugate. |
complex_calc | One operation: add, subtract, multiply, divide, conjugate, reciprocal, or integer power (De Moivre, exponent −1000..1000). Result in all three forms. |
complex_convert | to_polar (any input → modulus, argument rad/deg, polar + exponential strings) and to_rect (polar input → a+bi). |
complex_functions | Principal values of exp, log, sin, cos, tan, sinh, cosh, sqrt. Branch conventions are reported in the result note. |
complex_roots | All n n-th roots (n = 1..64): r^(1/n)·(cos((θ+2πk)/n) + i·sin((θ+2πk)/n)), k = 0..n−1, listed from the principal root. |
Every value is deterministic: computations keep raw IEEE doubles and round/snap floating-point dust only at the output boundary (10 decimal places by default, configurable via plugins.complex.roundPlaces).

a+bi (or a-bi, bi, a, bare i; j also accepted; whitespace around the operator and the suffix is tolerated; scientific notation works; the imaginary coefficient may be omitted — 1+i is 1+1i).r∠θ° with θ in degrees (the ° or deg suffix is optional; negative angles accepted; r must be ≥ 0).arg ∈ (-π, π]; log and sqrt report their branch convention in the result note.log(0) and division by zero return an honest valid: false with an explanation instead of guessing.plugins:
