in an Arduino calculation of a float variable (flow number, comma value), the result is always calculated without decimal places.

The calculation varFloat=1000/myFloat1 always yields 0.00



In the case of calculation operations, you have to specify the fixed numbers with a point as a float.

Example: instead of 1000 you specify 1000.0



Output is 0.75 MHz

  float frequency= float1000.0 / nsPulswidth );





Output is 0.00 MHz

  float frequency= float1000 / nsPulswidth );
