'''Suffixation''': a letter or a group of letters added to the end of a word to change its meaning.
::::::: ───── or, as used herein ─────
'''Suffixation''': the addition of a metric or "binary" metric suffix to a number, with/without rounding.
;Task:
Write a function(s) to append (if possible) a metric or a "binary" metric suffix to a
number (displayed in decimal).
The number may be rounded (as per user specification) (via shortening of the number when the number of
digits past the decimal point are to be used).
;Task requirements:
::* write a function (or functions) to add (if possible) a suffix to a number
::* the function(s) should be able to express the number (possibly with a suffix) in as many decimal digits as specified
::* the sign should be preserved (if present)
::* the number may have commas within the number (the commas need not be preserved)
::* the number may have a decimal point and/or an exponent as in: -123.7e-01
::* the suffix that might be appended should be in uppercase; however, the '''i''' should be in lowercase
::* support:
::::* the metric suffixes: '''K M G T P E Z Y X W V U'''
::::* the "binary" metric suffixes: '''Ki Mi Gi Ti Pi Ei Zi Yi Xi Wi Vi Ui'''
::::* the (full name) suffix: '''googol''' (lowercase) (equal to '''1e100''') (optional)
::::* a number of decimal digits past the decimal point (with rounding). The default is to display all significant digits
::* validation of the (supplied/specified) arguments is optional but recommended
::* display (with identifying text):
::::* the original number (with identifying text)
::::* the number of digits past the decimal point being used (or none, if not specified)
::::* the type of suffix being used (metric or "binary" metric)
::::* the (new) number with the appropriate (if any) suffix
::::* all output here on this page

;For instance, with this pseudo─code:
/* 1st arg: the number to be transformed.*/
/* 2nd arg: # digits past the dec. point.*/
/* 3rd arg: the type of suffix to use. */
a = '456,789,100,000,000' /* "A" has eight trailing zeros. */
say ' aa=' suffize(a) /* Display a suffized number to terminal.*/
/* The "1" below shows one decimal ···*/
/* digit past the decimal point. */
n = suffize(a, 1) /* SUFFIZE is the function name. */
n = suffize(a, 1, 10) /* (identical to the above statement.) */
say ' n=' n /* Display value of N to terminal. */
/* Note the rounding that occurs. */
f = suffize(a, 1, 2) /* SUFFIZE with one fractional digit */
say ' f=' f /* Display value of F to terminal. */
/* Display value in "binary" metric. */
bin = suffize(a, 5, 2) /* SUFFIZE with binary metric suffix. */
say 'bin=' bin /* Display value of BIN to terminal. */
win = suffize(a, 0, 2) /* SUFFIZE with binary metric suffix. */
say 'win=' win /* Display value of WIN to terminal. */
xvi = ' +16777216 ' /* this used to be a big computer ··· */
big = suffize(xvi, , 2) /* SUFFIZE with binary metric suffix. */
say 'big=' big /* Display value of BIG to terminal. */
would display:
aa= 456.7891T
n= 456.8T
f= 415.4Ti
bin= 415.44727Ti
win= 415Ti
big= 16Mi
