  Sample input:
2.3
  Sample output:
37

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

A simple conversion to enable web page proportions to be calculated to conform to golden ratio proportions etc, such calculations require pixels as the common measurement but responsive web pages are best constructed with Ems hence the need for this type of conversion.

Shouldn't that be:
Let([
x=type size ems; //input
r=Case(

x< .53; 8;
x< .59; 9;
x< .66; 10;
x< .73; 11;
x< .78; 12;
x< .84; 13;
x< .91; 14;
x< .98; 15;
x< 1.03; 16;
x< 1.09; 17;
x< 1.16; 18;
x< 1.23; 19;
x< 1.28; 20;
x<1.35; 21;
x< 1.43; 22;
x< 1.48; 23;
x< 1.55; 24;
x< 1.7; 26;
x< 1.9; 29;
x< 2.1; 32;
x< 2.23; 35;
x< 2.28; 36;
x< 2.33; 37;
x< 2.4; 38;
x< 2.5; 40;
x< 2.65; 42;
x< 2.88; 45;
