'''SHARP APL''' was a standalone version of APL offered by [[I.P. Sharp Associates]] (IPSA), who had previously offered APL interpretation as a timesharing service. IPSA employed many notable APL designers including [[Ken Iverson]], and SHARP APL was the source of many developments in [[flat array theory]]. | |||

=== Numeric types === | |||
SHARP originally supported only real numbers using double (8-byte) precision. Numbers were stored in one of three types: | |||
* Boolean, with one bit per value | |||
* Integer, with four bytes per value | |||
* Floating, with eight bytes per value | |||
[https://www.jsoftware.com/papers/satn40.htm SATN-40] describes the addition of complex numbers to SHARP APL. | |||
