Round Number (round)

Round a number by a user defined precision

Description

round supports a few different levels of precision:

Nearest decimal place

Syntax: 0.12345 (any numbers can be used)

If a decimal place is supplied then round will round your number to however many decimal places you specify. It doesn’t matter what digits you include in your precision value as the only thing which is used to drive the result is the position of the decimal point. Thus a precision value of 0.000 would perform the same rounding as 9.999.

Decimal places are always rounded to the nearest. --down and --up flags are not supported.

Nearest integer

Syntax: either 0 or 1 (either behaves the same)

This will round your value to the nearest whole number. For example 3.33 would be rounded to 3.

If --down flag is supplied then the remainder is dropped. For example 9.99 would then be rounded to 9 instead of 10.

If --up flag is is supplied then the the input value would always be rounded up to the nearest whole number. For example 3.33 would be rounded to 4 instead of 3.

Nearest multiple

Syntax: 50 (any integer greater than `1)

This will round your input value to the nearest multiple of your precision.

Like with nearest integer (see above), --down and --up will specify to round whether to always round down or up rather than returning the nearest match in either direction.

Usage

round value precision -> <stdout>
