RELERRName:
There may be some slight differences for this formula in other sources. Specifically,
where <y1> is a variable or a parameter; <y2> is a variable or a parameter; <y> is a variable or a parameter (depending on what <y1> and <y2> are) where the computed relative error values are stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional.
LET A = RELERR(A1,A2) LET X2 = RELERR(X1,X4) LET X2 = RELERR(X1-4,X2+6)
LET X = SEQUENCE 0.1 0.1 3 LET Y1 = X**2 LET Y2 = X**(1/2) LET Y3 = RELERR(Y1,Y2) SET WRITE DECIMALS 5 PRINT Y1 Y2 Y3The following output is printed: --------------------------------------------- Y1 Y2 Y3 --------------------------------------------- 0.01000 0.31622 -30.62277 0.04000 0.44721 -10.18033 0.09000 0.54772 -5.08580 0.16000 0.63245 -2.95284 0.25000 0.70710 -1.82842 0.36000 0.77459 -1.15165 0.49000 0.83666 -0.70746 0.64000 0.89442 -0.39754 0.81000 0.94868 -0.17121 1.00000 1.00000 0.00000 1.21000 1.04880 0.13321 1.44000 1.09544 0.23927 1.69000 1.14017 0.32533 1.96000 1.18321 0.39631 2.25000 1.22474 0.45566 2.56000 1.26491 0.50589 2.89000 1.30384 0.54884 3.24000 1.34164 0.58591 3.61000 1.37840 0.61817 4.00000 1.41421 0.64644 4.41000 1.44913 0.67139 4.84000 1.48323 0.69354 5.29000 1.51657 0.71331 5.76000 1.54919 0.73104 6.25000 1.58113 0.74701 6.76000 1.61245 0.76147 7.29000 1.64316 0.77459 7.84000 1.67332 0.78656 8.41000 1.70293 0.79751
