Fix
Gets the integer of a value by rounding off digits to the right of the decimal point.
Format
Fix(<expression>)
Parameter
Return value
Returns an integer value gotten by rounding off digits to the right of the decimal point.
Description
Gets the integer value of the expression specified in the <expression> parameter by rounding off digits to the
right of the decimal point.
If a negative value is specified in the <expression> parameter, the Fix function will return the least negative
integer value greater than the specified negative value. This contrasts with the Int function that returns the
greatest negative value that does not exceed the specified negative value. For example, Int(-7.2) returns -8
and Fix(-7.2) returns -7.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a value is assigned to the return value variable or the variable is not used in an expression, a "Syntax error"
error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• None.
Example
Changes the double precision real number value of a measurement result to an integer by rounding off digits
to the right of the decimal point.
The result is shown below.
