StringFromReal() Function

In a script, you can convert an real value to a string value by using the StringFromReal() function.

You can also specify to:

• Round the value to a specified precision.

• Pass the value in exponential notation.

This can be used, for example, to show text together with real values or for showing real numbers with exponential notation.

Syntax

result = StringFromReal (number, precision, type)

Parameters

number

A literal value, analog tagname, or numeric expression.

precision

Specifies how many decimal places are to be used. A literal integer value, integer tagname, or integer expression.

type

Specifies if the exponential notation is to be used. A literal string, message tagname, or string expression.

"f" - Use floating point notation.

"e" - Use exponential notation with lowercase "e".

"E" - Use exponential notation with uppercase "E".

Example(s)

StringFromReal(263.355, 2,"f") returns "263.36".

StringFromReal(263.355, 2,"e") returns "2.63e2".

StringFromReal(263.55, 3,"E") returns "2.636E2".

StringFromReal(0.5723, 2,"E") returns "5.72E-1".
