Examples:
InStr (3, "Bananas", "na") -> 3
InStr (4, "Bananas", "na") -> 5
InStr (6, "Bananas", "na") -> 0
5.2.3 Len - Length of a string
Len(S)
yields the length of the string expression
S
, i.e. the number of characters
in
S
(not counting the terminating zero). The result is of type
Integer
.
Examples:
Len ("Bananas") -> 7
Len ("A + B = ") -> 8
Len ("")
-> 0
5.2.4 Val - Numerical value of a string
Val(S)
yields the value of the string expression
S
interpreted as a numeric
constant. S may contain leading blanks, one sign, a decimal point, and a power of
ten part with or without sign. Blanks within the number are not allowed.
Interpretation ends with the first character that cannot be part of a legal GeoB
ASIC
numeric constant representation. If
S
does not represent a number, the result of
Val(S)
is 0. The result is of always of type
Double
.
Examples:
Val ("1.5") -> 1.5
Val (" +7.3e-4") -> 0.00073
Val ("-2E5xyz") -> -200000.0
Val ("X") -> 0.0
Val (" -3") -> -3.0
