You can always type a formula in the editor. Most "traditional" keyboard shortcuts for math work. Selection is important.
· Use *
for multiply, /
for divide, and ^
for exponentiation.
· Most familiar functions work using the most common abbreviation: sin
, random
, floor
, ln
, log
, asin
, exp
, sgn
, to name a few. Functions require parentheses around their arguments, as in sin(x)
.
· Use to get the cursor out of an exponent, root, or the denominator of a fraction.
pi
and then immediately type another letter or a number, Fathom doesn't know that you mean pi
to be its own word. After typing pi
, press one of the arrow keys or the space bar (or *
if you want to multiply). After the p appears, you can type anything you want, and the p will remain p.· Entering one vertical bar "|" makes a pair of absolute-value bars.
· The double-quote key makes a pair of quotes.
· The open parenthesis "(
" makes a pair of parentheses.
· When you type if(
you get a complete (though empty) if-statement, with three parts for you to fill in. Type the condition (for example, income > 100000
), then press Tab to move to the results (result-if-true goes on the top, result-if-false on the bottom). If you want the results to be words (also known as strings), you must surround them with quotation marks.
· When you have more than two results, instead of nesting if-statements, you can use the switch function. This is useful for recoding attributes. It takes an optional expression inside parentheses and then evaluates each of any number of true/false expressions to determine which value to return. To add an alternative, press Insert (Win) z+Option+Return (Mac) on your keyboard.
· To insert something in the beginning, don't click to place your cursor; instead, arrow to the beginning before adding to the existing formula.
