NAME

Language::Befunge::IP::lib::CPLI - Complex numbers extension

DESCRIPTION

The CPLI fingerprint (0x43504C49) allows to do complex numbers operations.

FUNCTIONS

new

Create a new CPLI instance.

Complex operations

• ($r, $i) = A( $ar, $ai, $br, $bi )

  Push ($ar+i*$ai) + ($br+i*$bi) back onto the stack (complex addition)

• ($r, $i) = D( $ar, $ai, $br, $bi )

  Push ($ar+i*$ai) + ($br+i*$bi) back onto the stack (complex division)

• ($r, $i) = M( $ar, $ai, $br, $bi )

  Push ($ar+i*$ai) + ($br+i*$bi) back onto the stack (complex multiplication)

• ($r, $i) = S( $ar, $ai, $br, $bi )

  Push ($ar+i*$ai) + ($br+i*$bi) back onto the stack (complex subtraction)

• V( $r, $i )

  Push back absolute value of complex $r + i* $i.

Output

• O( $r, $i )

  Output complex number $r + i * $i.
