Boards that Support the Function
Operation ASCII characters given to it is changed into the Float value (In VB, Single value).
Format
(VB.NET)
Dim Ret As Integer
Dim Str As String
Dim FltData As Single
Ret = GpCnvStrToFlt(Str, FltData)
(C)
DWORD Ret;
char *Str;
float FltData;
Ret = GpCnvStrToFlt(Str, &FltData);
(C#)
uint Ret;
string Str
float FltData;
Ret = gpib.CnvStrToFlt(Str, out FltData);
(Python)
Ret = ctypes.c_ulong()
Str = ctypes.create_string_buffer(xxxx) # (xxxx is the string length)
FltData = ctypes.c_float()
Ret.value = GpibPy.GpCnvStrToFlt(Str, ctypes.byref(FltData))
Mode Master mode / Slave mode
Parameters
Str : A string to change.
Characters
to change into the Float value (In
VB, Single value)
is specified.
There is no problem even if a header is
contained in this characters.
And, a capital letter, small letter is judged
as the same one character.
FltData : Changed Float value (In VB, Single value, return value)
Ret : Return value
0 : Normal completion
255 : Illegal call
(See "Return Values" for details.)
Notes
1 This function does a change on the following condition.
When there is [<Header>+<The characters which shows numerical value>] or [< The characters which shows numerical value>]
*Refer to the complement of GpCnvStrToDbl() for the details of the condition that it faces in the data block.
2 This function can be used even if it doesn't call GpIni().
3 The condition of 1. is applicable when it is removed when a header and so on is set up by the GpCnvSettings function.
