        decide on the sine of temp.

    To decide what real number is the cosine of (N - a number):
        let temp be N as a fixed point number;
        let temp be temp real plus 90.0000;
        decide on the sine of temp.

    To decide what real number is the arccosine of (N - a real number):
        let result be the arcsine of N;
        decide on 90.0000 real minus result.
