Press and select round to round a number to a given number of places.

Press and select iPart to return the integer part of a number.

Press and select fPart to return the fractional (decimal) part of a number. This is the same as the number minus its integer part.

Press and select int to return the greatest integer less than or equal to the argument.

Press and select abs to find the absolute value of a real or complex number.

Press and select sign to find the sign of a number x as x/|x| for nonzero x and 0 if x is 0.

Press and select min to return the smaller of the two arguments.

Press and select max to return the larger of the two arguments.

Press and select modulo to find the remainder when the first argument is divided by the second.

The options Round, min, max, and mod take two arguments each, separated by a comma, and enclosed by a pair of perentheses.

These functions can be evaluated on each element in a list. For example,
fpart { 1.23 , 4.32 , 1.5 , -2.333 } returns { .23 .32 .5 -.333 }.
