Converts a string in a field to a single-precision floating point variable
| Call | |
| #include <vv_singl.h> | |
| int dc_tosingle(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_tosingle() 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 single-precision floating point value. The single-precision floating point value is placed in the data variable. |

|
| Cautions
No error checking is performed on the input string. The function assumes that vf_single() 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(). |
