| − | These functions convert between different types. There are also some [[Internal_functions/Numeric_functions|numeric functions]] that can be classified in this category, namely: <tt>Ceil, Floor, Float, Int</tt> and <tt>Round</tt>.
| |
| − |
| |
| − | * {{ScriptFunction|Value|v2.07|Value(string)}}
| |
| − | : Converts a decimal string to its associated numeric value.
| |
| − | : ''Examples:''
| |
| − | Value ("-2.7") = -2.7
| |
| − |
| |
| − | * {{ScriptFunction|HexValue|v2.07|HexValue(string)}}
| |
| − | : Converts a hexadecimal string to its associated numeric value.
| |
| − | : ''Examples:''
| |
| − | HexValue ("FF00") = 65280
| |
| − |
| |
| − | * {{ScriptFunction|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"
| |
| − |
| |
| − | * {{ScriptFunction|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:
| |
| − | : <tt>%[flags][width][.precision]f</tt>
| |
| − | : ''flags'':
| |
| − | :: <tt>- </tt> left align (instead right align)
| |
| − | :: <tt>+ </tt> always print the +/- sign
| |
| − | :: <tt>0 </tt> padding with leading zeros
| |
| − | :: <tt>' '</tt> print a blank instead of a "+"
| |
| − | :: <tt># </tt> 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'
