Int_to_Decimal
INT err;
s ':=' "1234";
err := RTL_Decimal_to_Int16_(s, 4, r); ! R = 1234;
s ':=' %hB1323334;
err := RTL_Decimal_to_Int16_(s, 5, r); ! R = -1234;
Int_to_Decimal
The Int_to_Decimal functions convert an integer to a character string whose contents
represent a decimal number. You can specify the format in which the sign of the
number is stored in the character string. These functions are not available in the native
CRE library.
int16
int32
int64
contains the value to convert.
str
is a string of up to 19 bytes that contains the result of the conversion.
len
specifies the length of str in bytes.
sign_type
specifies how to represent the sign in the result. Table 7-5 on page 7-29 shows the
literals you can use for
sign_type when you call Int_to_Decimal.
