round()

Returns the rounded number to the specified precision.

Syntax

round(number [, precision])

Parameters

Returns

The rounded number to the specified precision.

Round is different from the bin() function in that the round() function rounds a number to a specific number of digits while the bin() function rounds the value to an integer multiple of a given bin size. For example, round(2.15, 1) returns 2.2 while bin(2.15, 1) returns 2.

Examples

round(2.98765, 3)   // 2.988
round(2.15, 1)      // 2.2
round(2.15)         // 2 // equivalent to round(2.15, 0)
round(-50.55, -2)   // -100
round(21.5, -1)     // 20
