Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The deccvasc() function converts a value held as printable characters in a C char type into a decimal type number.

mint deccvasc(strng_val,  len,  dec_val)

	char  *strng_val;

	mint  len;

	dec_t  *dec_val;

 



strng_val  

is a pointer to a string whose value deccvasc() converts to a decimal value. 


len

is the length of the strng_val string. 


dec_val

is a pointer to the decimal structure where deccvasc() places the result of the conversion. 

The character string, strng_val, can contain the following symbols:

• A leading sign, either a plus (+) or minus (-)
• A decimal point, and digits to the right of the decimal point
• An exponent that is preceded by either e or E. You can precede the exponent by a sign, either a plus (+) or minus (-).

The deccvasc() function ignores leading spaces in the character string.
