NAME ^

Language::Befunge::lib::FIXP - Fixed point operations extension

VERSION ^

version 5.000

DESCRIPTION ^

The FIXP fingerprint (0x4649585) allows to do fixed point operations.

FUNCTIONS ^

new

Create a new FIXP instance.

Angle operations

Those functions expect their arguments times 10000, and their result follow the same convention (this gives 4 digits of precision). All angles are in degrees.

$r = B( $v )

Push back acos($v) on the stack. See precision convention above.

$r = C( $v )

Push back cos($v) on the stack. See precision convention above.

$r = I( $v )

Push back sin($v) on the stack. See precision convention above.

$r = J( $v )

Push back asin($v) on the stack. See precision convention above.

$r = T( $v )

Push back tan($v) on the stack. See precision convention above.

$r = U( $v )

Push back atan($v) on the stack. See precision convention above.

Arithmetic functions

$r = A( $a, $b )

Push back $a & $b on the stack.

$r = O( $a ,$b )

Push back $a | $b on the stack.

$r = X( $a, $b )

Push back $a xor $b on the stack.

Numeric functions

$r = D( $v )

Push back rand($v) on the stack.

$r = N( $v )

Push back 0-$a on the stack (negation of argument).

$r = P( $v )

Push back $v * pi on the stack.

$r = Q( $v )

Push back sqrt $v on the stack.

$r = R( $a, $b )

Push back $a ** $b on the stack.

$r = S( $v )

Push back the sign of $v on the stack.

$r = V( $v )

Push back abs($v) on the stack.
