  • can be any string containing characters, numbers, symbols, blankspaces etc.
  • If argument is directly entered in the command, it should be enclosed in double quotes (e.g. "Name").
  • Argument indicates the number of characters to be displayed from a text string. should be >0.
  • If >'length of text', Calci displays the entire text.
  • If is omitted, Calci assumes it to be 1.

Examples

Consider the following examples as input to LEFT() function.

Wel-Come
JOHN SMITH
123*123 
=LEFT(A1,8) : Displays first 8 characters in a string from cell A1. Displays Wel-Come as the output. 
=LEFT(A2,5) : Displays first 5 characters in a string from cell A2. Displays JOHN  as the output. Space Character is also counted.
=LEFT(A3,4) : Displays first 4 characters in a string from cell A3. Displays 123* as the output.
