💅 float_to_long(9) 💅

hey bestie 🫶 this is the float_to_long(9) page from the Kernel API Manual, and it's short, sweet, and here to turn your hardware float reading into an integer. iykyk ✨

🌸 NAME 🌸

float_to_long — converts an ieee754 reading from hardware to an integer. literally that's the whole job, and it ate 💅

✨ SYNOPSIS ✨

long float_to_long (u32 data , u32 precision );

🎀 ARGUMENTS 🎀

• data — the value read from the hardware 🫶
• precision — the units it multiplies up to, eg. 1000 = milli, 1000000 = micro ✨

💖 RETURN 💖

the converted integer reading. slay, no cap 💅

🦋 DESCRIPTION 🦋

okay so depending on the measurement type, the hardware returns an ieee754 floating point value in either volts, amps, or celsius. this function converts that into an integer in a smaller unit such as micro-amps or milli-celsius. and before you stress: the hardware does not return NaN, so you do not need to consider that at all 🙅‍♀️💀
