Character Functions
Arguments
blob a binary large object.
encoding Optional quoted string that specifies an encoding. Supported encodings are: utf-8, utf-16le,
utf-16be, us-ascii, iso-8859-1, and ascii-hex.
Notes
The optional argument ascii is intended to make conversions of blobs containing normal ASCII data
simpler when the data might contain CR, LF, or TAB characters (for example) and those characters do
not need any special attention.
Blob To Matrix(blob, "type", bytes, "endian", )
Description
Creates a matrix by converting each byte in the blob to numbers.
Returns
A matrix that represents the blob.
Arguments
blob A blob or reference to a blob.
"type" A quoted string that contains the named type of number. The options are int, uint, or
float.
bytes Byte size of the data in the blob. Options are 1, 2, 4, or 8.
"endian" A quoted string that contains a named type that indicates whether the first byte is the most
significant. Options are as follows:
– big indicates that the first byte is the most significant.
– little indicates that the first byte is the least significant.
– native indicates that the machine’s native format should be used.
nCols Optional. Specify the number of columns in the matrix. The default value is 1.
Char(x, , )
Description
Converts an expression or numeric value into a character string.
Returns
A string.
Arguments
x an expression or a numeric value. An expression must be quoted with Expr(). Otherwise, its
evaluated value is converted to a string.
width optional number that sets the maximum number of characters in the string.
decimal optional number that sets the maximum number of places after the decimal that is included
in the string.
Note
The width argument overrides the decimal argument.
