Float in tcl

WebThe Tcl language provide 4 commands : int arg : The integer part of arg is determined, and then the low order bits of that integer value up to the machine word size are returned as an integer value. ceil arg: Returns the smallest integral floating-point value (i.e. with a zero fractional part) not less than arg. WebIf you need to control the display precision of floating point values, use format (eg format %.12g $x ). The default value for $tcl_precision is 0, meaning that when Tcl converts a number to a string, the fewest digits necessary to distinguish a floating point number from its nearest neighbours.
