f Prints float values. o Prints an octal value. s Prints a text string. Here we use printf to format our output: $ awk 'BEGIN{ x = 100 * 100 printf "The result is: %e\n", x }' Here is an example of printing scientific numbers. We are not going to try every format specifier....

. In systems where the integer type has 64-bit size, the float most likely does not have a mantissa large enough to hold the value without loss of precision. If those systems also have a native 64-bit C int type (most UNIX-like systems don't), the only way to use the I pack ...
