設定例

■VB.NET用

Dim StrSize, Ret As Integer

Dim Str As New String("", 256)

Dim FltData As Single

StrSize = 256

FltData = 0.000123

Ret = GpCnvFltToStr(Str, StrSize, FltData)

 (実行結果)

Str      : "+0.12300E-003"

StrSize   : 13

■C言語用

DWORD StrSize, Ret;

char Str[256];

float FltData;

StrSize = sizeof(Str);

FltData = 0.000123;

Ret = GpCnvFltToStr(Str, &StrSize, FltData);

 (実行結果)

Str      : "+0.12300E-003"

StrSize   : 13

■C#用

uint StrSize, Ret;

StringBuilder Str = new StringBuilder(256);

float FltData;

StrSize = 256;

FltData = 0.000123;

Ret = gpib.CnvFltToStr(Str, out StrSize, FltData);

 (実行結果)

Str      : "+0.12300E-003"

StrSize   : 13

■Python用

StrSize, Ret = ctypes.c_ulong(), ctypes.c_ulong()

Str = ctypes.create_string_buffer(256)

FltData ctypes.c_float()

StrSize.value = len(Str)

FltData.value = 0.000123

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

 (実行結果)

Str : "+0.12300E-003"

StrSize : 13
