FORMAT/de

= (**COPIED FROM ENGLISH PAGE**) === Action

Formats a numeric string.

 

 

Syntax

target = FORMAT(source, "mask")

 

 

Remarks

target	The string that is assigned with the formatted string.
source	The source string that holds the number.
mask	The mask for formatting the string.   When spaces are in the mask, leading spaces will be added when the length of the mask is longer than the source string. " " '8 spaces when source is "123" it will be " 123". When a + is in the mask (after the spaces) a leading + will be assigned when the number does not start with the - sign. "+" with number "123" will be "+123". When zero's are provided in the mask, the string will be filled with leading zero;s. " +00000" with 123 will be " +00123" An optional decimal point can be inserted too: "000.00" will format the number 123 to "001.23" Combinations can be made but the order must be : spaces, + , 0 an optional point and zero's.

 

When you do not want to use the overhead of the single or double, you can use the LONG. You can scale the value by a factor 100.

Then use FORMAT to show the value.

For example : Dim L as Long, X as Long , Res as Long

L = 1

X = 2

Res = L / X

Now this would result in 0 because an integer or Long does not support floating point.

But when you scale L with a factor 100, you get :

L= 100

X = 2

Res = L / X

 

Now Res will be 50. To show it the proper way we can use FORMAT. Format works with strings so the variables need to be converted to string first.

 

Dim S1 as string * 16 : s1 = Str(Res)

Print Format(s1,"000.00")
