"FIXP" Some useful fixed point math functions

Fingerprint ID:0x46495850

This fingerprint, from RC/Funge-98, implements fixed-point arithmetics. It provides the following commands:

A : a b — (a AND b)

Performs bitwise AND.

B : (10000×n) — (10000×arccos(n))

Calculates arccosine of n, in degrees. Reflects for invalid argument.

C : (10000×n) — (10000×cos(n))

Calculates cosine of n, in degrees.

D : n — x

Pushes a random number between 0 and n-1, or between n and -1 if n is negative.

I : (10000×n) — (10000×sin(n))

Calculates sine of n, in degrees.

J : (10000×n) — (10000×arcsin(n))

Calculates arcsine of n, in degrees. Reflects for invalid argument.

N : n — -n

Pushes the negate of n.

O : a b — (a OR b)

Performs bitwise OR.

P : n — (π×n)

Pushes n multiplied by pi.

Q : n — sqrt(n)

Pushes the square root of n. Reflects if n is negative.

R : a b — a^b

Pushes the b-th power of a. Reflects if a and b are zero.

S : n — sign(n)

Pushes +1 if n is positive, -1 if negative, or 0 if zero.

T : (10000×n) — (10000×tan(n))

Calculates tangent of n, in degrees.

U : (10000×n) — (10000×arctan(n))

Calculates arctangent of n, in degrees. Reflects for invalid argument.

V : n — abs(n)

Pushes the absolute value of n.

X : a b — (a XOR b)

Performs bitwise XOR.

All commands discards the fraction of result value, except that result value scaled by 10000 is rounded to nearest integer.
