Data Conversion

6–8 110838 Tandem Computers Incorporated

Parameters

lpElementValue Pointer to where the start of the converted string is placed.

The string may be preceded by a minus sign and contain a

decimal point (such as -12, +42.76). Leading zeros and

insignificant trailing zeros are not returned.

lpDisplayNumber Pointer to the Tandem display numeric to be converted.

nDisplayNumberLength Length of the Tandem display numeric (including any

separate sign).

nSignType Display numeric sign type of the Tandem display

numeric:

TDMGW_CONV_NOT_SIGNED = No sign

TDMGW_CONV_SLI_SIGNED = Leading embedded sign

TDMGW_CONV_STI_SIGNED = Trailing embedded sign

TDMGW_CONV_SLS_SIGNED = Leading separate sign

TDMGW_CONV_STS_SIGNED = Trailing separate sign

nDecimalPlaces Number of implied decimal places in the Tandem display

numeric.

TdmgwConvTdmTwosCompToCfText

This function converts strings from Tandem two’s complement data representation to

CF_TEXT clipboard format (null terminated string).

Function Prototype

void FAR PASCAL TdmgwConvTdmTwosCompToCfText

(char far * lpElementValue, out

void far * lpTwosCompNumber, in

int nTwosCompNumberLength, in

int nSignType, in

int nDecimalPlaces); in

If nDecimalPlaces is negative, then lpElementValue is scaled up after conversion.

Effectively lpElementValue is multiplied by ten to the power of the absolute value of

nDecimalPlaces. For details on the scaling of two’s complement numbers, see the

Tandem Data Definition Language (DDL) Reference Manual.

Parameters

lpElementValue Pointer to where the start of the converted string is

placed. The string may be preceded by a minus sign

and contain a decimal point (such as -12, +42.76).

Leading zeros and insignificant trailing zeros are not

returned.

lpTwosCompNumber Pointer to the two’s complement number.

nTwosCompNumberLength Length of Tandem two’s complement number in bytes

(must be 1, 2, 4, or 8).
