Notes

A minus sign in front makes a number negative: -2.5, -1/4. A whole number, a dash and a fraction is one mixed number: 2-1/4 is 2¼; to subtract, put spaces round the minus: 2 - 1/4 is 1¾. Fractions with fractions and whole numbers stay exact (1/4+1/8 is 3/8, 2 - 1/4 is 1¾), and so do the functions that can keep them so: ABS, SIGN, SQR, MIN, MAX, CLAMP, ROUND, FLOOR, CEIL, TRUNC, %, POW to a whole power, SQRT when the root is exact, LERP, INVERSELERP and REMAP by a fraction, and a FOR loop's steps. With a decimal, they become one. Feet and inches stay feet and inches with feet and inches, times or divided by a whole number or a fraction (2*1'6" is 3'), and in ABS, MIN, MAX, CLAMP, %, LERP and REMAP; ROUND, FLOOR, CEIL and TRUNC make them whole inches. Feet and inches divided by feet and inches is a fraction, and so is INVERSELERP of them. Otherwise they become the drawing's units: in a millimetre drawing, 3'6" is 1066.8, and 1'+1/2 is 305.3; in a drawing in inches, a plain number is inches, so 1'+1/2 is 1' ½". Functions that need an ordinary number (SIN, LOG, DOUBLE, INT …) take them as one, in the drawing's units. To change between inches and millimetres, use TOMM and TOIN.
