[Gretl-users] Re: how to avoid "useless" 0 after the decimal

To be frank, the kind of expression "abs(d)<0.00001 ? 0 : d" sounds to me not that much intuitive - anyway, less than zeroifclose() stuff - but probably it's just lack of experience. It's basically just a compact if-block which you can read out like this: Is abs(d) smaller than 1e-5 ? ( <- note the literal question mark in the syntax!) If yes, set it to zero - or else if not, then leave it at d (the old value). This is borrowed from C I believe. The cool thing in hansl (gretl scripting) is that it also works directly with matrices if you use the dot-operators. Example (which I cannot test right now): <hansl> matrix M = ( I(3) .> 0 ) ? -2 : 0 # note the .> print M </hansl> cheers sven _______________________________________________ Gretl-users mailing list -- gretl-users(a)gretlml.univpm.it To unsubscribe send an email to gretl-users-leave(a)gretlml.univpm.it Website: https://gretlml.univpm.it/postorius/lists/gretl-users.gretlml.univpm.it/
