Prototype
procedure FloatToStr(input : real; var output : array[23] of char);
Returns
- 3 if input number is NaN
- 2 if input number is -INF
-
1 if input number is +INF
- 0 if conversion was successful
Description
Converts a floating point number to a string.
Parameters :
-
input: floating point number to be converted
- output: destination string
The output string is left justified and null terminated after the last digit.
Note: Given floating point number will be truncated to 7 most significant digits
before conversion.
Requires Nothing.
Example
var ff1, ff2, ff3 : real;
txt : array[23] of char;
...
ff1 := -374.2;
ff2 := 123.456789;
ff3 := 0.000001234;
FloatToStr(ff1, txt); // txt is "-374.2"
FloatToStr(ff2, txt); // txt is "123.4567"
FloatToStr(ff3, txt); // txt is "1.234e-6"
Prototype
function Dec2Bcd(decnum : byte) : byte;
Returns Converted BCD value.
Description
Converts input number to its appropriate BCD representation.
Parameters :
-
decnum: number to be converted
Requires Nothing.
Example
var a, b : byte;
...
a := 22;
b := Dec2Bcd(a); // b equals 34
