Examples
“Results are frequently expressed in "petaflops," indicating that a quadrillion floating-point operations—a type of scientific calculation—are completed each second.”
The Wall Street Journal: Cray to Take On Supercomputer After IBM's Exit
“Based on data submitted so far, Mr. Dongarra said, the Sunway machine has "credible" sustained performance of about 795 teraflops--or trillion floating-point operations per second, a measure of scientific calculations based on standard tests.”
The Wall Street Journal: China Supercomputer Uses Homegrown Chips
“Unlike today's supercomputers, with speeds that are measured in petaflops - a quadrillion sustained floating-point operations per second - the next generation will be measured in exaflops - a quintillion, or one million trillion floating point operations per second.”

“In fact, I've rambled at length on my theories of subgenre boundaries - you see, sub-genres are floating-point variables, not binaries.”
MIND MELD: What's Your Favorite Sub-Genre of Science Fiction and/or Fantasy?
“For example, Excel uses floating-point math, which can sometimes give people disconcerting results.”
“The way you add two integers is quite different to the way you add two floating-point numbers, or a float and an integer, or two matrices.”
“You have to manage your own storage, and it's up to you to preserve type safety; code sequences such as 123 3.0 + integer addition when there's a floating-point number on top of the stack have undefined behaviour.”
“Intel's Pentium chips sported a tiny error in floating-point calculation that led to a product recall.”
“In economics, the parallel is this: If the unitary cost of technology ("per megabyte" or "per megabit per second" or "per thousand floating-point operations per second") is halving every 18 months, when does it come close enough to zero to say that you've arrived and can safely round down to nothing?”
