# USAGE:Edit

ROUND n /even /down /half-down /floor /ceiling /half-ceiling /to scale

# DESCRIPTION:Edit

Returns the nearest integer. Halves round up (away from zero) by default.

ROUND is a function value.

# ARGUMENTSEdit

**n**-- The value to round (Type: number money time)

# REFINEMENTSEdit

**/even**-- Halves round toward even results**/down**-- Round toward zero, ignoring discarded digits. (truncate)**/half-down**-- Halves round toward zero**/floor**-- Round in negative direction**/ceiling**-- Round in positive direction**/half-ceiling**-- Halves round in positive direction**/to**-- Return the nearest multiple of the scale parameter**scale**-- Must be a non-zero value (Type: number money time)

# (SPECIAL ATTRIBUTES)Edit
