LenB

Function

Return the byte count of character string or numerical value.

This command is available in Ver.1.6.* or higher.

Syntax

LenB(Data )

Guaranteed entry

Data
Specify a character string and numerical value and variable. All data types can be specified.

Return value

Return the byte counts of Data by Integer type data.

Description

Return the byte count of character string or numerical value.

When Data is a character string
Return the byte count of character string
A single-byte character is regarded as one byte, and a double-byte character is regarded as two bytes.
To count both a single-byte character and a double-byte character as one character, use Len command.

When Data is a variable

Return the byte count of a variable type.
For example, if Integer type variable are specified, “4” is returned. However, if String type variable are specified, the return value is the byte counts of the stored character string.

When Data is a numerical value

For example, if “10” is specified, the data is determined as Integer type, and then “4” will be returned. If "10.1" is specified, the data is determined as Double-precision variable of type real, and then "8" will be returned.
Real number of numerical value is determined as Double-precision variable of type real, not determined as Floating-point variable of type real.

Example

'!TITLE "Obtain the byte count of data"
'Store I-type variable data in the variant type array

Sub Main

	Dim vv as Variant
	Dim ISize As Integer

	iSize = LenB(I0)
	vv = CreateArray(iSize*3)

	For n=0 to 3
		For i=0 to iSize-1
			vv(n*iSize+i) = (I[n] >> i*8) And 0xFF
		Next
	Next
