void Str_WriteFloat(float n, byte decimal, char text[], word offset);
Sub Str_WriteFloat(n As Single,decimal As Byte,ByRef text As Char,offset
As Word)
Description
The floating point number n is converted to an ASCII string with decimal number of decimal digits after the
period. The result is stored in the string text with an offset of offset. The offset parameter is used to change
a string after a specified number (offset) of characters and leave the beginning of the string intact.
Parameter

If offset has the value STR_APPEND ( 0xffff ) then the length of the destination string is assumed as
offset. In this case the source string is copied behind the destination string.
