I'm going to guess its impossible to get f 3.120 --> 3 (decimal places) because
of:
] 3.12
3.1200000000000001
this verb seems better than m12 in
C:\j601\system\extras\help\phrases\representations.htm
decimals=: (] i. 1:)@: (]= <.) @: (( 10^i.13) * ]) NB. max 13 decimal places
hard coded.
m12=: <.@(10&^.)@(('.'&~: # ]) &.": % ])
m12 3.212
16
decimals 3.212
3
the decimals verb can get a bit flakey with high input, but its ok for
currencies
decimals 134.9999999999
10
decimals 131324.9999999999
0

Subject: Re: [Jprogramming] decimal conversions
I would like a verb f such that f returns a literal that is exactly the number
that was typed. ie:
f 3.12
3.12
f 3.120
3.120
": 3.12
3.1200000000000001
I need this info to simply count the number of decimals given, so if there is
an alternate way of doing this, and the above is impossible, then help is
appreciated.
