# AviSynth Syntax - Conversion functions

Conversion functions convert between different types. There are also some numeric functions that can be classified in this category, namely: `Ceil, Floor, Float, Int` and `Round`.

- Value | v2.07 | Value(string)

Converts a decimal string to its associated numeric value.

Examples:

    Value ("-2.7") = -2.7

- HexValue | v2.07 | HexValue(string)

Converts a hexadecimal string to its associated numeric value.

Examples:

    HexValue ("FF00") = 65280

- Hex | v2.60 | Hex(int)

Converts a numerical value to its hexadecimal value string. See Colors for more information on specifying colors.

Examples:

    Hex (10824234) = "A52A2A"

- String | v2.07 | String(float / int [, string format_string])

Converts a variable to a string. If the variable is float or integer, it first converts it to a float and then uses format_string to convert the float to a string. The syntax of format_string is as follows:

- `%[flags][width][.precision]f`
  - width: the minimum width (the string is never truncated)
  - precision: the number of digits printed
  - flags:
    - `-` left align (instead right align)
    - `+` always print the +/- sign
    - `0` padding with leading zeros
    - `' '` print a blank instead of a “+”
    - `#` always print the decimal point

You can also put arbitrary text around the format_string as defined above, similar to the C-language printf function.

Examples:

    Subtitle( "Clip height is " + String(last.height) )
    Subtitle( String(x, "Value of x is %.3f after AR calc") )
    Subtitle( "Value of x is " + String(x, "%.3f") + " after AR calc") )
    # same as above
    String(1.23, "%f") = '1.23'
    String(1.23, "%5.1f") = ' 1.2'
    String(1.23, "%1.3f") = '1.230'
    String(24, "%05.0f") = '00024'
