filehandle/stream = a valid variable set with the OpenFile, WriteFile command, or OpenTCPStream (v1.52+)
myFloat = a floating point variable |
|
Once you've opened a disk file (or stream) for writing, use this command to write a single floating point number to the file. Note, each value written uses 4 bytes.
Streams can only be used in Blitz Basic v1.52 or greater. |
