real in string

How do I do to turn a variable real into string? Thanks

Use this function: Num2Str Syntax str Num2Str (real number,int characters,int decimals,int separator1,int separator2) Description Converts the decimal number specified by number to a text string. The minimum number of characters required in the text is specified by characters, and the required number of decimals is specified by decimals. The decimal separator required in the text is specified by separator1, and the thousands separator required in the text is specified by separator2. Examples Num2Str(12345.6,10,2,2,1) returns “12.345,60”. Num2Str(12345.6,1,0,1,0) returns “12346”. Notes The possible values for separator1 are: ‘1’: a ‘.’ (point) used as decimal separator ‘2’: a ‘,’ (comma) used as decimal separator. The possible values for separator2 are: ‘0’: no thousands separator ‘1’: a ‘.’ (point) used as thousands separator ‘2’: a ‘,’ (comma) used as thousands separator ‘3’: a ’ ’ (space) used as thousands separator. MorphX replaces any invalid parameter with a standard value.
