i figured the heading wouldn't affect the read in unless im mistaken but i could easily remove that. And the spaces could be taken out using sed '/^$/d' file.txt
so im still having trouble with reading from the file and using bc. I keep getting parse error.

having a bash script convert ft to meters with 1 decimal

What is the correct syntax to limit the number of decimals to 1 or 0 in a bash script? Here is the partial code I have which works, but if I echo $meters, it has 4 or 5 decimals: METERS=`echo "$FEET * 0.3048" | bc` I read about scale and length in the bc man page, but I can't seem to get the...

NAME
Int64 - 64-bit integers. Module Module Int64 Documentation Module Int64 : sig end 64-bit integers. This module provides operations on the type int64 of signed 64-bit integers. Unlike the built-in int type, the type int64 is guaranteed to be exactly 64-bit wide on all platforms. All arithmetic operations over int64 are taken modulo 2^{64 Performance notice: values of type int64 occupy more memory space than values of type int , and arithmetic operations on int64 are gener- ally slower than those on int . Use int64 only when the application requires exact 64-bit arithmetic. val zero : int64 The 64-bit integer 0. val one : int64 The 64-bit integer 1. val minus_one : int64 The 64-bit integer -1. val neg : int64 -> int64 Unary negation. val add : int64 -> int64 -> int64 Addition. val sub : int64 -> int64 -> int64 Subtraction. val mul : int64 -> int64 -> int64 Multiplication. val div : int64 -> int64 -> int64 Integer division. Raise Division_by_zero if the second argument is zero. This division rounds the real quotient of its arguments towards zero, as specified for Pervasives.(/) . val rem : int64 -> int64 -> int64 Integer remainder. If y is not zero, the result of Int64.rem x y satisfies the following property: x = Int64.add (Int64.mul (Int64.div x y) y) (Int64.rem x y) . If y = 0 , Int64.rem x y raises Division_by_zero . val succ : int64 -> int64 Successor. Int64.succ x is Int64.add x Int64.one . val pred : int64 -> int64 Predecessor. Int64.pred x is Int64.sub x Int64.one . val abs : int64 -> int64 Return the absolute value of its argument. val max_int : int64 The greatest representable 64-bit integer, 2^{63 - 1. val min_int : int64 The smallest representable 64-bit integer, -2^{63. val logand : int64 -> int64 -> int64 Bitwise logical and. val logor : int64 -> int64 -> int64 Bitwise logical or. val logxor : int64 -> int64 -> int64 Bitwise logical exclusive or. val lognot : int64 -> int64 Bitwise logical negation val shift_left : int64 -> int -> int64 Int64.shift_left x y shifts x to the left by y bits. The result is unspecified if y < 0 or y >= 64 . val shift_right : int64 -> int -> int64 Int64.shift_right x y shifts x to the right by y bits. This is an arithmetic shift: the sign bit of x is replicated and inserted in the vacated bits. The result is unspecified if y < 0 or y >= 64 . val shift_right_logical : int64 -> int -> int64 Int64.shift_right_logical x y shifts x to the right by y bits. This is a logical shift: zeroes are inserted in the vacated bits regardless of the sign of x . The result is unspecified if y < 0 or y >= 64 . val of_int : int -> int64 Convert the given integer (type int ) to a 64-bit integer (type int64 ). val to_int : int64 -> int Convert the given 64-bit integer (type int64 ) to an integer (type int ). On 64-bit platforms, the 64-bit integer is taken modulo 2^{63, i.e. the high-order bit is lost during the conversion. On 32-bit platforms, the 64-bit integer is taken modulo 2^{31, i.e. the top 33 bits are lost during the conversion. val of_float : float -> int64 Convert the given floating-point number to a 64-bit integer, discarding the fractional part (truncate towards 0). The result of the con- version is undefined if, after truncation, the number is outside the range [ Int64.min_int , Int64.max_int ]. val to_float : int64 -> float Convert the given 64-bit integer to a floating-point number. val of_int32 : int32 -> int64 Convert the given 32-bit integer (type int32 ) to a 64-bit integer (type int64 ). val to_int32 : int64 -> int32 Convert the given 64-bit integer (type int64 ) to a 32-bit integer (type int32 ). The 64-bit integer is taken modulo 2^{32, i.e. the top 32 bits are lost during the conversion. val of_nativeint : nativeint -> int64 Convert the given native integer (type nativeint ) to a 64-bit integer (type int64 ). val to_nativeint : int64 -> nativeint Convert the given 64-bit integer (type int64 ) to a native integer. On 32-bit platforms, the 64-bit integer is taken modulo 2^{32. On 64-bit platforms, the conversion is exact. val of_string : string -> int64 Convert the given string to a 64-bit integer. The string is read in decimal (by default) or in hexadecimal, octal or binary if the string begins with 0x , 0o or 0b respectively. Raise Failure int_of_string if the given string is not a valid representation of an integer, or if the integer represented exceeds the range of integers representable in type int64 . val to_string : int64 -> string Return the string representation of its argument, in decimal. val bits_of_float : float -> int64 Return the internal representation of the given float according to the IEEE 754 floating-point ``double format'' bit layout. Bit 63 of the result represents the sign of the float; bits 62 to 52 represent the (biased) exponent; bits 51 to 0 represent the mantissa. val float_of_bits : int64 -> float Return the floating-point number whose internal representation, according to the IEEE 754 floating-point ``double format'' bit layout, is the given int64 . type t = int64 An alias for the type of 64-bit integers. val compare : t -> t -> int The comparison function for 64-bit integers, with the same specification as Pervasives.compare . Along with the type t , this function compare allows the module Int64 to be passed as argument to the functors Set.Make and Map.Make . OCamldoc 2012-06-26 Int64(3o)
