val pretty : ?on_negative:[ `Blow_up | `Normal | `Print_dir ] -> float -> string

pretty-print a float using no more than five characters, using abberviations k, m, g, t.

if on_negative is not set to `Normal then the resulting is never over four chars but upon negative number we either:

• raise a failure
• or print "<0"

val to_string_hum : float -> string

val order_of_magnitude_difference : float -> float -> int

order_of_magnitude_difference a b by how many orders of magnitude do a and b differ? The return value is non-negative.

examples:

• order_of_magnitude_difference 11. 1001. = 2
• order_of_magnitude_difference 1001. 11. = 2
• order_of_magnitude_difference 131. 11. = 1
• order_of_magnitude_difference 200. 0.003 = 5
