Convert floating-point numbers to strings

HCL OneDB™ ESQL/C can automatically convert floating-point column values (data type of DECIMAL(n), FLOAT, or SMALLFLOAT) between database columns and host variables of character type char, varchar, string, or fixchar. When HCL OneDB ESQL/C converts a floating-point value to a character string whose buffer is not large enough to hold the full precision, HCL OneDB ESQL/C rounds the value to fit it in the character buffer.
