Numbers
Rounding functions
Several functions are available for rounding fractional numeric values to integral values or a specific number of fractional digits:
round(z,n): returns z rounded to n (optional) decimal places. If n is omitted, it returns z rounded to the nearest integer (n is assumed to be zero). If n<0, it returns z rounded to n places to the left of the decimal point. For example,
round(π-2πi)returns 3-6iround(-(π-2πi))returns -3+6i.
trunc(z): returns the integer part of z by removing the fractional part. For example,
trunc(2.7)returns 2trunc(-2.2)returns -2
floor(z): returns the greatest integer ≤ z
floor(π-2πi)returns 3-7ifloor(-(π-2πi))returns -4+6i
ceil(z): returns the smallest integer ≥ z
ceil(π-2πi)returns 4-6iceil(-(π-2πi))returns -3+7i
