A floating point number. |
define external float function FP_v value stream numeric string
Used to initialize floating point values by converting a character string representing a floating point number into a float value. If the string does not represent a floating point number, the float value for NaN (not a number) is returned. FP_v converts the case-insensitive representations of the following strings into their floating point value counterparts:
The following code demonstrates how to use FP_v to initialize the stream my-float using any digit that matches the specified pattern:
...
find white-space (digit+("."digit*)?)=>found-float
local float my-float
set my-float to FP_v found-float
