Pretty printing of numbers that are rounded and in SI notation (eg 3.25n)

ScaledNumbersOutput

This package provides a utility function for pretty printing numbers. The to_SI(val; sigdigits) takes a number and converts it to the a string using SI scaling prefixes. For example:

julia> to_SI(75.2e10)
"752G"

julia> to_SI(0.000000021)
"21n"

By default numbers are rounded to 5 digits but that can be chosen:

julia> to_SI(1/9)
"0.11111"

julia> to_SI(1/9, sigdigits=7)
"0.1111111"

The following scale factors are supported:

Symbol	Scaling Factor
P	10^15
T	10^12
G	10^9
M	10^6
k	10^3
m	10^-3
u	10^-6
n	10^-9
p	10^-12
f	10^-15
a	10^-18
