cnum()#

Purpose#

cnum(expr)

Converts expr to a number (integer).

Note

If the expression does not contain a numerical value, the following rule applies: the best match as the number is returned. For example “1x234” will return the number 1 and “Test123” will return 0. Zero is always returned if the there is no number at the start of the string. This also is the case for empty strings.

Example#

cnum(3+2);
