APL2's extensions to [[ISO 8485:1989]] were standardised as [[ISO-IEC-13751]]. APL2 supports entry of [[complex number]]s in the following forms:
APL2's extensions to [[ISO 8485:1989]] were standardised as [[ISO-IEC-13751]]. APL2 supports entry of [[complex number]]s in the following forms:
# Real and imaginary part separated by the letter <source lang=apl inline>J</source> and no spaces, e.g. <source lang=apl inline>0J1</source>
# Real and imaginary part separated by the letter <syntaxhighlight lang=apl inline>J</syntaxhighlight> and no spaces, e.g. <syntaxhighlight lang=apl inline>0J1</syntaxhighlight>
# Magnitude and angle in degrees separated by the letter <source lang=apl inline>D</source> and no spaces, e.g. <source lang=apl inline>1D90</source>
# Magnitude and angle in degrees separated by the letter <syntaxhighlight lang=apl inline>D</syntaxhighlight> and no spaces, e.g. <syntaxhighlight lang=apl inline>1D90</syntaxhighlight>
# Magnitude and angle in radians separated by the letter <source lang=apl inline>R</source> and no spaces, e.g. <source lang=apl inline>1R1.5708</source>
# Magnitude and angle in radians separated by the letter <syntaxhighlight lang=apl inline>R</syntaxhighlight> and no spaces, e.g. <syntaxhighlight lang=apl inline>1R1.5708</syntaxhighlight>
No further core language features have been added, with improvements instead consisting of powerful [[Quad name]]s.
