format_numbers() formats 0 as NaN x 10^-Inf

[iofarm]

Passing x = 0 to format_numbers() produces NaNs in scientific and engineering notation:

format_numbers(0, format = "sci")
#> [1] "$NaN \\times 10^{-Inf}$"

format_numbers(0, format = "engr")
#> [1] "$NaN \\times 10^{-Inf}$"

I assume this is because the power is calculated using log10(x). This can be easily avoided using decimal notation:

format_numbers(0, format = "dcml")
#> [1] "$0$"

However, it would be convenient to not have to handle zeroes specially, especially when x is programmatically generated and may or may not be 0.
