Var The string that is assigned with the result.
Source A variable of the type single that must be formatted.
Mask The formatting mask . ###.##
The # sign is used to indicate the number of digits before and after the decimal point. Normal rounding is used.

When you don't need rounding the result, use the & sign instead of the # sign after the point.

When you want leading zero's use the 0 character before the point.

Example

Dim S As Single , Targ As String * 16
'The FUSING() function formats a single into a string in order to 'represent it better without all the digits after the point

'assign single
S = 99.4999
Targ = Fusing(s , ##.#)
Print Targ
'with the # mask, you can provide the number of digits before and after 'the point
'the result should be 99.5

'with a 0 before the point, you can indicate how many digits you want to 'have filled with zeros

Targ = Fusing(s , 000.#)
'the result should be 099.5

'When you dont want that the result is rounded, you can use the & indicator

Targ = Fusing(s , 000.&&)
'result should be 099.49

'note that if the number of digits you provide is not enough to store the 'result result is extended automatically

'Also note that the - sign will use one digit of the mask too

S = -99.12
Targ = Fusing(s , 00.&&)
'result is -99.12
