dc_todouble()

Converts a string in a field to a double-precision floating point variable

Call
#include <vv_doubl.h>
int dc_todouble(stp, datap, dfldp, cvbufp)
UCHAR *stp	Pointer to string with user's field input
PTR datap	Pointer to variable to receive converted field input
DFIELDPTR dfldp	Pointer to a data field structure
PTR cvbufp	Pointer to a data conversion buffer
Returns
1	Success. This is the only return value for this function
Description dc_todouble() makes a copy of the field string in the conversion buffer. All embedded blanks and thousands separators are deleted from the buffer, and the resulting string is converted to a double value. The double-precision floating point value is placed in the data variable.

Cautions The data type must be double, not float. No error checking is performed on the input string. dc_todouble() assumes that vf_double() has already validated the string. This function calls atof(). You may have to link the appropriate floating point library for your compiler to resolve atof().
