intmatcher: Avoid conversion from double to float and vice versa

This fixes some clang warnings:

    src/classify/intmatcher.cpp:48:49: warning:
      implicit conversion loses floating-point precision:
      'double' to 'const float' [-Wimplicit-float-conversion]
    src/classify/intmatcher.cpp:405:34: warning:
      implicit conversion loses floating-point precision:
      'double' to 'float' [-Wimplicit-float-conversion]
    src/classify/intmatcher.cpp:405:64: warning:
      implicit conversion increases floating-point precision:
      'float' to 'double' [-Wdouble-promotion]
