Dear Webmaster,
I came across a topic in my studies of the Arduino system that may need correction (constrain() - Arduino Reference). The item resides under mathematical operations. From what I understood, being a newbie to this, it looked to be in error. The following is a partial copy of the page below.
Constrain(x, a, b) Function
x: if x is between a and b
a: if x is less than a
b: if x is greater than b
Example:
sensVal = constrain(sensVal, 10, 150);
// limits range of sensor values to between 10 and 150
"should not it say if x is greater than a, and x is lesser than b?" "That's what then note part of the code says."
Corrections, suggestions, and new documentation should be posted to the Forum.
