You can set x87 to round each operation result to 32-bit or 64-bit.
With this setting in operates internally exactly on those sizes.
Operating internally on 80-bits is just the default setting, because it is the best for naive users, who are otherwise prone to computing erroneous results.
This is the same reason why the C language has made "double" the default precision in constants and intermediate values.
Unless you do graphics or ML/AI, single-precision computations are really only for experts who can analyze the algorithm and guarantee that it is correct.
