If \(\left|x\right|\) is greater than .Machine$double.xmax, then as.numeric(x) returns Inf or -Inf but no warning is given.

Examples

a <- as.brob(1:10)
a <- cbrob(a, as.brob(10)^1e26)
a
#>  [1] +exp(0)          +exp(0.69315)    +exp(1.0986)     +exp(1.3863)    
#>  [5] +exp(1.6094)     +exp(1.7918)     +exp(1.9459)     +exp(2.0794)    
#>  [9] +exp(2.1972)     +exp(2.3026)     +exp(2.3026e+26)
as.numeric(a)
#>  [1]   1   2   3   4   5   6   7   8   9  10 Inf

as.complex(10i + a)
