(3) Numeric value/character string conversion functions
The following functions convert a numeric expression into a character string or vice versa.
STRS(n)
n: numeric value
Converts numeric value n into a character string.
(A hexadecimal value is preceded by $.)
Examples: A$ =STRS$(— 12)
The character string ‘‘—12’’ is returned as A$.
B$ =STR$(70* 33)
The character string ‘‘2310"’ is returned as BS.
C$ =STR$(1200000 * 5000)
The character string “‘6E +09”’ is returned as C$.
Note:
A positive integer displayed or printed is preceded by a single space which indicates that the plus sign
(+) is valid but has been omitted. However, this space is deleted when the integer is converted into
a string by the STR$ function.
VAL(x$)
x$; character string
Converts a character string into a numeric value.
Example: A= VAL (‘123°’)
The string ‘‘123’’ is converted into the numeric value 123.
A=VAL (“‘$FF”’)
A string ‘‘$FF”’ is converted into the numeric value 255.
ASC(x$)
x$: character string
Returns the numeric value which is the ASCII code for the first character of string X$.
Examples: X = ASC(‘‘A’’)
Returns the numeric value 65, which is the ASCII code for character ‘‘A’’.
Y = ASC(‘‘SHARP”’)
Returns the numeric value 83, which is the ASCII code for the first character of
the string ““SHARP”’.
