Hi,

  I want to define a macro, \doifoneelse, that checks if the first 
argument is 1 or not. It should work for decimals and strings also. 
So,

\doifoneelse{1}{a}{b}  gives a
\doifoneelse{1.5}{a}{b} gives b
\doifonelese{string}{a}{b} gives b

Can someone suggest how to define this?

Thanks,
Aditya

Ah, it is already defined in context. I was so fixated upon using 
\ifnum and \ifcase that I did not see \doifelse. Sorry about the 
noise.

\def\doifoneelse#1#2#3{\doifelse{1}{#1}{#2}{#3}}
\starttext
\doifoneelse{1}{a}{b}      gives a
\doifoneelse{1.5}{a}{b}    gives b
\doifoneelse{string}{a}{b} gives b
\stoptext

Cheers, Peter

Thanks Peter,

  I ended up using

\def\doifoneelse#1{\doifelse{#1}{1}}

which saves a few keystrokes :)

\def\doifoneelse{\doifelse{1}}

or 

\def\doifoneelse{\doifelse1}

saves you even more keystrokes and also a bit of runtime (measured in nanoseconds)
