設定例

■VB.NET用

Dim Ret As Integer

Dim Str As String

Dim FltData As Single

Str = "DV +0.123E-3"

FltData = 0

Ret = GpCnvStrToFlt(Str, FltData)

 (実行結果)

FltData: 0.000123

■C言語用

DWORD Ret;

char Str[256];

float FltData;

lstrcpy(Str, "DV +0.123E-3");

FltData = 0;

Ret = GpCnvStrToFlt(Str, &FltData);

 (実行結果)

FltData: 0.000123

■C#用

uint Ret;

string Str;

float FltData;

Str = "DV +0.123E-3";

FltData = 0;

Ret = gpib.CnvStrToFlt(Str, out FltData);

 (実行結果)

FltData: 0.000123

■Python用

Ret = ctypes.c_ulong()

Str = ctypes.create_string_buffer(256)

FltData = ctypes.c_float()

Str.value = b"DV +0.123E-3"

FltData.value = 0

Ret.value = GpibPy.GpCnvStrToFlt(Str, ctypes.byref(FltData))

 (実行結果)

FltData: 0.000123
