: ''BASIC 1.0 & 1.1''
: '''FUNCTION''': Rounds <numeric expression> to a number of decimal places or to the power of ten specified by <integer expression>. If <integer expression> less than zero, the <numeric expression> is rounded to give an absolute integer with <integer expression> number of zeros before the decimal point.

Returns -1 if <numeric expression> is less than 0, returns 0 if <numeric expression> = 0, and returns 1 if <numeric expression> is greater than zero.
: Rounds n to a number of decimal places or to the power of ten specified by i. If i is negative, the n is rounded to give an absolute integer with i zeros before the decimal point.: Example'''Associated keywords''':ABS
