MKD$, MKI$, MKS$
Function
MKD$(double precision expression)
MKI$( integer expression)
MKS$(single precision expression)
Converts numeric values to string values.
Any numeric value that is placed in a direct file buffer with an
LSET
or RSET statement must be converted to a string.
These
3 functions are the inverse of CVD, CVI, and CVS. The
byte values that make up the number are not changed; only
1
byte, the internal data-type specifier, is changed so that numeric
data can be placed in
a string variable.
MKD$ returns an 8-byte string; MKI$ returns a 2-byte string;
and MKS$ returns a 4-byte string.
Example
LSET AVGS. = MKSS(0.123)
