Usage

## S4 method for signature 'brob'
is.infinite(x)
## S4 method for signature 'glub'
is.infinite(x)
## S4 method for signature 'brob'
is.finite(x)
## S4 method for signature 'glub'
is.finite(x)

Arguments

x

vector of class brob or glub

Details

Examples

is.infinite(brob(c(1,4,Inf)))

is.infinite(glub(3,Inf))
is.infinite(glub(Inf,3))


is.infinite(exp(1e300))
is.infinite(brob(1e300))
# (Brobdingnagian infinity is bigger than regular infinity ;-)
