Numerical accuracy and form of results in editorial computingAll calculations in editorial computing are performed - whenever possible - in double precision, i.e. within an accuracy of 15-16 significant digits. By default, the results are displayed with 13-14 significant digits. The `accuracy' parameter in SURVO.APU has no influence in editorial computing. However, an ACCURACY specification controls the display accuracy. ACCURACY=<4,5,...,or 16> gives # of significant digits in results of editorial computing. Another form is ACCURACY=-n where n is 1,2,3,... gives the # of decimals. Examples: ................................................................................ ACCURACY=7 A=0.12345678901234567 A=0.1234568 ................................................................................ ACCURACY=-2 A=12345.6789 B=-12 A.=12345.68 B.=-12.00 When extremely small or large values of results in editorial computing are needed in accurate form, a ' (single quotation mark) in the control column on those lines of values implies the results to be displayed in exponential form (1.123456789012345e+123).In versions 1.24+ it is possible to make calculations in multiple precision up to about a million digits.
