Description

Str returns a string which represents the value of X. X can be any numerical type. The actual declaration of Str is not according to pascal syntax, and should be

procedure Str(var X: TNumericType[:NumPlaces[:Decimals]];var S: String)

Where the optional NumPlaces and Decimals specifiers control the formatting of the string: NumPlaces gives the total width of the string, and Decimals the number of decimals after the decimal separator char.
