Singular

The size function in Singular for a matrix is very misleading, though may be useful is some situations. Further as per the man page of [url=https://www.singular.uni-kl.de/Manual//4-0-3/sing_395.htm#SEC435]size[/url], it does not accept bigintmat.

The best way to get the size of a matrix / intmat / bigintmat is to use nrows and ncols functions.

[code]
> bigintmat mymat[2][4] = 1,2,3,4,5,6,8;
> nrows (mymat);
> ncols (mymat);
[/code]

Hi all,

if I call size for a bigintmat, it will cause an error.

[code]
> bigintmat mymat[2][4] = 1,2,3,4,5,6,8;
> size(mymat);
? size(`bigintmat`) failed
? expected size(`bigint`)
? expected size(`number`)
? expected size(`resolution`)
? expected size(`string`)
? expected size(`poly`)
? expected size(`vector`)
? expected size(`ideal`)
? expected size(`module`)
? expected size(`matrix`)
? expected size(`intvec`)
? expected size(`intmat`)
? expected size(`list`)
? expected size(`ring`)
[/code] How can I get the total number of entries of a bigintmat besides explicit conversion to intmat? I'd like to be able to call size(mymat) where mymat is of type bigintmat.
