<h3>NAME
</h3> modf - extract signed integral and fractional values from
floating-point number
<h3>SYNOPSIS
</h3> #include <math.h>
double modf(double x, double *iptr);
<h3>DESCRIPTION
</h3> The modf() function breaks the argument x into an integral
part and a fractional part, each of which has the same
sign as x. The integral part is stored in iptr.
<h3>RETURN VALUE
</h3> The modf() function returns the fractional part of x.

Ubicom SX18 thru SX52, PIC 16c5X compatibile, 50 to 75 MIPS microcontrollers! |
Robotics nuts!Check out http://users.frii.com/dlc/robotics/projects/botproj.htm from Dennis Clark. This guy ROCKS! He has made (and sells but also releases code, docs, etc...) for a number of cool little robotic modules including whiskers, IR proximity detect and remote control, Sonar proximity detect, PWM, Servo, compass. Most of these use the little PIC 12C508 controller which costs basically nothing and is soooo tiny.The 4 servos, 2400 baud serial servo controller is a wonder of magic and he sells the programmed chip for $8. Wow! |
