Conversion functions
These 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. 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
- 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
- width: the minimum width (the string is never truncated)
- precision: the number of digits printed
- 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'
