WebFor floating-point arithmetic, the mantissa was restricted to a hundred digits or fewer, and the exponent was restricted to two digits only. The largest memory supplied offered 60 000 digits, however Fortran compilers for the 1620 settled on fixed sizes such as 10, though it could be specified on a control card if the default was not satisfactory. WebThat’s too much power to leave with an algorithm, and too much control to cede to those who tend those algorithms. If recommendation algos aren’t shared then we need - by legislation, if ...
