c - 分数を浮動小数点に変換する

Question

分数を浮動小数点に変換して比較に使用しようとしています。しかし、値が小さすぎるため、ブール変数の結果に対して true を返します。私の変換は正しいですか？または、私が知らない別の方法でそれを行う必要がありますか?

テストケース:

  // result is -0.0074
  float coilh0re = fr32_to_float(GO_coil_H[0].re)*0.8f;
  // result is -0.0092
  float coilrefundamental = fr32_to_float(CoilEepromData.coilboardhspule.reFundamental);
  // result is -0.01123
  float coilh0re2 = fr32_to_float(GO_coil_H[0].re)*1.2f;
  -0.0074>-0.0092> -0.01123

ここにコードの抜粋があります

       bool resultA  = fr32_to_float(GO_coil_H[0].re)*0.8f < fr32_to_float(CoilEepromData.coilboardhspule.reFundamental)  ? 1 : 0;
       bool resultB  = fr32_to_float(CoilEepromData.coilboardhspule.reFundamental)  <= fr32_to_float(GO_coil_H[0].re)*1.2f ? 1 : 0;

       bool resultAB = !(resultA & resultB); // always true

       bool resultC  =  fr32_to_float(GO_coil_H[1].re)*0.8f < fr32_to_float(CoilEepromData.coilboardhspule.reHarmonic) ? 1:0;
       bool resultD  = fr32_to_float(CoilEepromData.coilboardhspule.reHarmonic)  <= fr32_to_float(GO_coil_H[1].re)*1.2f ? 1:0;

       bool resultCD = !(resultC & resultD); // always true

       bool resultE  =  fr32_to_float(GO_coil_H[0].im)*0.8f < fr32_to_float(CoilEepromData.coilboardhspule.imFundamental)? 1 : 0;
       bool resultF  =  fr32_to_float(CoilEepromData.coilboardhspule.imFundamental) <= fr32_to_float(GO_coil_H[0].im)*1.2f ? 1 : 0;

       bool resultEF = !(resultE & resultF);// always true

       bool resultG  =  fr32_to_float(GO_coil_H[1].im)*0.8f < CoilEepromData.coilboardhspule.imHarmonic ? 1 : 0;
       bool resultH  =  fr32_to_float(CoilEepromData.coilboardhspule.imHarmonic) <= fr32_to_float(GO_coil_H[1].im)*1.2f ? 1 : 0;

       bool resultGH = !(resultG & resultH);// always true

        if(! ((fr32_to_float(GO_coil_H[0].re)*0.8f < fr32_to_float(CoilEepromData.coilboardhspule.reFundamental)) && (fr32_to_float(CoilEepromData.coilboardhspule.reFundamental) <= fr32_to_float(GO_coil_H[0].re)*1.2f) )
