532 equal divisions of the octave (abbreviated 532edo or 532ed2), also called 532-tone equal temperament (532tet) or 532 equal temperament (532et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 532 equal parts of about 2.26 ¢ each. Each step represents a frequency ratio of 21/532, or the 532nd root of 2.

532edo is only consistent to the 5-odd-limit since harmonic 7 is about halfway between its steps. As 532 = 19 × 28, 532edo tempers out both the enneadeca, which sets 6/5 to 5\19, and the oquatonic comma, which sets 5/4 to 9\28. Therefore, it can be conceptualized as superset of 19edo and 28edo. In addition to the enneadecal and oquatonic, it also supports untriton in the 5-limit.

The patent val tempers out 65625/65536 (horwell comma) and 390625/388962 (dimcomp comma) in the 7-limit. The 532d val tempers out 4375/4374 (ragisma) and 703125/702464 (meter). In the 11-limit, 532d val supports the hemienneadecal temperament.
