# NOT RUN {
x = c(1, 1.2, 12.78749, pi, 0.00000012)
format_fixed(x, digits=3) #default zero_digits=1
format_fixed(x, digits=3, zero_digits=2)
format_fixed(x, digits=3, zero_digits=NULL)

x_sd = sd(iris$Sepal.Length/10000, na.rm=TRUE)
format_fixed(x_sd, dig=6)
format_fixed(x_sd, dig=3, zero_digits=2) #default only_round=FALSE
format_fixed(x_sd, dig=3, zero_digits=2, only_round=TRUE)
options("crosstable_only_round"=TRUE)
format_fixed(x_sd, dig=3, zero_digits=2) #override default
options("crosstable_only_round"=NULL)

x2 = mtcars$mpg/max(mtcars$mpg)
x2 = c(0.01, 0.1001, 0.500005, 0.00000012)
