+PI(= 3.1415926535897932384626...) Calculation Program
+
+
+    ver. LG1.1.2-MP1.5.2a Nov. 1999
+
+
+Files:
+    fftsg_h.c   : FFT Package - split-radix   - use no work areas
+    pi_fftcs.c  : PI Calculation Program - memory save version
+                  -- use rdft() in "fft*g_h.c"
+	readme.txt  : this file
+    Makefile    : - for gcc modify for your own compiler.
+
+To Compile:
+    Check macros in "pi_fftcs.c" and modify if necessary.
+    DBL_ERROR_MARGIN is very impotant parameter.
+    If DBL_ERROR_MARGIN is very small then efficiency will be bad.
+    If DBL_ERROR_MARGIN >= 0.5 then it may calculate a wrong result.
+
+Example Compilation:
+    GNU:
+        gcc -O -funroll-loops -fomit-frame-pointer pi_fftcs.c fftsg_h.c -lm -o pi_css5
+    SUN:
+        cc -fast pi_fftcs.c fftsg_h.c -lm -o pi_css5
+    HP:
+		aCC -fast pi_fftcs.c fftsg_h.c -lm -o pi_css5
+    Microsoft:
+        cl -O2 pi_fftcs.c fftsg_h.c -o pi_css5
+
+Relationship between Number of Digits and FFT Length:
+    ndigit = nfft*log_10(R), R >= 10000 or 1000
+    R is a radix of multiple-precision format.
+    R depends on DBL_ERROR_MARGIN and 
+    FFT+machine+compiler's tolerance.
+
+Number of Floating Point Operations:
+    pi_fftcs.c + fftsg_h.c:
+        42*nfft*(log_2(nfft))^2           [Operations]
+
+Memory Use:
+    pi_fftcs.c:
+        nfft*(6*sizeof(short int)+3*sizeof(double))   [Bytes]
+
+AGM Algorithm:
+  ---- a formula based on the AGM (Arithmetic-Geometric Mean) ----
+    c = sqrt(0.125);
+    a = 1 + 3 * c;
+    b = sqrt(a);
+    e = b - 0.625;
+    b = 2 * b;
+    c = e - c;
+    a = a + e;
+    npow = 4;
+    do {
+        npow = 2 * npow;
+        e = (a + b) / 2;
+        b = sqrt(a * b);
+        e = e - b;
+        b = 2 * b;
+        c = c - e;
+        a = e + b;
+    } while (e > SQRT_SQRT_EPSILON);
+    e = e * e / 4;
+    a = a + b;
+    pi = (a * a - e - e / 2) / (a * c - e) / npow;
+  ---- modification ----
+    This is a modified version of Gauss-Legendre formula
+    (by T.Ooura). It is faster than original version.
