I am porting some FORTRAN to R in which an Inf triggers an if(). The
trigger is infinite on exp(lgamma(OVER)). What is the canonical R
style of determining OVER when exp(OVER)== Inf? The code structure
that I am

porting is best left intact--so I need to query R somehow to the value
of OVER that causes exp(lgamma(OVER)) to equal Inf.

On my system,

exp(lgamma(171)) is about first to equal Inf.

.Machine$double.xmax = lgamma(OVER),

but I am not sure how to invert or solve for OVER

Thanks.
