StrFromReal(numValue,numPrecision, { strType | f | e | E } )

numValue

The numerical value to be converted.

numPrecision

The number of decimal places to be shown in the resulting string. Please note that the value will be rounded rather than truncated.

strType

A single-character code that specifies how the resulting string should be formatted, as described in the following table:

Value of strType	Description
f	Formatted in floating-point notation.
e	Formatted in exponential notation with a lower-case "e".
E	Formatted in exponential notation with an upper-case "E".

Returned value

This function returns a string representation of the given numerical value, with the specified precision and notation.
