Aug 7, 2025 · Like Tcl, it interprets variable substitution, command substitution, double quotes and braces. Unlike Tcl, it interprets anything that looks like a number as a number, anything that looks like boolean as boolean, provides operators and functions, and requires that literal string values be enclosed in double quotes or braces. The variable's value will be used as the operand. entier() coerces a number to an integer of appropriate size to hold it without truncation. 5 and above). If the first two characters of string are ``0x'' then string is expected to be in hexadecimal form; otherwise, if the first character of string is ``0'' then string is expected to be in octal form; otherwise, string is expected to be in decimal form.
