Format number to 2 decimal places

Question

I would like to know how can I output a number with 2 decimal places, without rounding the original number.

For example:

2229,999 -> 2229,99

I already tried:

FORMAT(2229.999, 2)
CONVERT(2229.999, DECIMAL(4,2))

Answer 1

When formatting number to 2 decimal places you have two options TRUNCATE and ROUND . You are looking for TRUNCATE function.

Examples:

Without rounding:

TRUNCATE(0.166, 2)
-- will be evaluated to 0.16

TRUNCATE(0.164, 2)
-- will be evaluated to 0.16

With rounding:

ROUND(0.166, 2)
-- will be evaluated to 0.17

ROUND(0.164, 2)
-- will be evaluated to 0.16

Answer 2

You want to use the TRUNCATE command.

Answer 3

How about CAST(2229.999 AS DECIMAL(6,2)) to get a decimal with 2 decimal places

Answer 4

Just use

format(number, qtyDecimals)
sample: format(1000, 2)
result 1000.00

Answer 5

This is how I used this is as an example:

CAST(vAvgMaterialUnitCost.`avgUnitCost` AS DECIMAL(11,2)) * woMaterials.`qtyUsed` AS materialCost

Answer 6

Show as decimal Select ifnull(format(100.00, 1, 'en_US'), 0) 100.0

Show as Percentage Select concat(ifnull(format(100.00, 0, 'en_US'), 0), '%') 100%
