differences between .sage and .spyx in numerical evaluation -


the question seems basic, i'm sorry not find answer in documentation.

the content of both files test.sage , test.spyx identical; it's just

a = 1/sqrt(2) print

if run test.sage with

$ sage test.sage

i get

1/2*sqrt(2)

but outcome different if run file test.spyx with

$ sage test.spyx

where get

compiling test.spyx... 0.707106781187

how can prevent sage numerically evaluating 1/\sqrt(2) in .spyx mode?

(i asked question on ask.sagemath.org got no answer yet...)
