Convert Real variable into String

Question

How can I convert a real declared variable into a string variable? Is there any function like IntToStr()? RealToStr() function won't work.

Answer 1

There is a bunch of conversion routines in SysUtils unit, ie FloatToStr and other FloatTo* functions. Also see the Format function.

Answer 2

A really old method uses the 'Str' procedure, which has two parameters: the first is a real or integer, and the second is a string variable, into which the formatted number will be placed.

Examples:

i:= 1;
str (i, a);   // a = '1'
r:= 1.5;
str (r:2, a); // a = '1.50'
