Basically, we look at the following cases: >>> 1.0001 ** -5 # doctest: +SKIP 0.99950014996500702 >>> 0.9999 ** -5 # doctest: +SKIP 1.000500150035007 >>> (-1.0001) ** -5 # doctest: +SKIP -0.99950014996500702 >>> (-0.9999) ** -5 # doctest: +SKIP -1.000500150035007 >>> 1.0001 ** -6 # doctest: +SKIP 0.99940020994401269 >>> 0.9999 ** -6 # doctest: +SKIP 1.0006002100560125 >>> (-1.0001) ** -6 # doctest: +SKIP 0.99940020994401269 >>> (-0.9999) ** -6 # doctest: +SKIP 1.0006002100560125 etc. We run the tests with values a very small epsilon away from 1: small enough that the result is indistinguishable from 1 when rounded to nearest at the output precision. We check that the result is not erroneously rounded to 1 in cases where the rounding should be done strictly away from 1. cSstt|j|tj|ƒƒS)N)Zmake_mpfZ mpf_pow_intZ_mpf_rr)ŚxŚnŚrr r r ŚpowrCsz'test_pow_epsilon_rounding..powr))ré)iˆiø rréé’’’’ééū’’’iś’’’rN) rrr rr rZ round_ceilingZ round_floorr )r%ZinprecZoutprecZpos10001Zpos09999Zneg10001Zneg09999r$r r r Śtest_pow_epsilon_rounding#sš r+)ZmpmathZ mpmath.libmprrr!r+r r r r Śs
