- 03:34, 25 February 2024 Marshall talk contribs created page Tolerant comparison (Created page with "'''Tolerant comparison''' is an inexact form of comparison used to mitigate the impact of floating-point rounding error on programs. It considers two numbers equal when their relative difference is smaller than a parameter called the '''comparison tolerance''', and accessed with the system variable <syntaxhighlight lang=apl inline>⎕CT</syntaxhighlight>. In addition to the comparison functions, tolerance applies to Match and Not Match, Floor, C...")

A '''character''' is a scalar array representing a unit of text. In current APLs this generally means a Unicode wikipedia:code point, while historically various custom character sets were used. These accomodated typical text as well as APL code, usually with one byte per character. Characters and numbers are the two basic...")

Numbers and characters were the only possible element types in APL0 and remain the basic data types in modern APLs. In addition to quantities for computation, they are used to represent Booleans (0 and 1) and indices. Numeric operations may be subject to floating-point rounding and comparison tolerance. Traditionally, APL provides only one user-visib...")
